What is Vacuum Pump Filter?

Vacuum pump filters are specialized filters used in vacuum pump systems to remove contaminants from the air or fluid being processed. They are crucial for maintaining the cleanliness and efficiency of the pump and the overall system. These filters can capture particles, separate liquid droplets, adsorb gases, and eliminate odors, depending on their specific design and filtration mechanisms. Regular maintenance and replacement of vacuum pump filters are necessary to ensure continuous and reliable operation.

How many Types of Vacuum Pump Filters are there?

There exist four primary types of vacuum pump filters; they include:

Inlet Filters

This type of vacuum pump filtration system is often installed at a position inline before the vacuum pump intake.They are made to protect a variety of vacuum pumps from contamination as a result of particulates like:

Stray fibers、Bagging film fragments、Dust commonly found in industrial manufacturing set up In vacuum pump inlet filter, the gas flow enters the exterior body of the filter then goes via the filter element from the exterior to interior.Finally, it leaves the filter system to the vacuum pump.There are various types of filter element suitable for different applications.However, a pleated polyester or paper element seems to be the ideal inlet filter element for dusty uses.The pleating provides a large surface area for the stream of gas to go through.

Exhaust Filters

Exhaust filters commonly find application on oil sealed rotary vane vacuum pumps.The primary role of this type of vacuum pump filter is to minimize or eliminate oil mist that often form due to operation of the vacuum pump.Vacuum pump exhaust filters help in maintaining vacuum pump exhaust clear of all noticeable oil mist, even if it is soaked with oil.The vacuum pump may expel the exhaust gas into a clean area or it may be recirculated into the process.This prevents the necessity to run exhaust pipes and duct work outside.Exhaust filters vacuum pump are fitted with highly efficient filter cartridge that constantly clears out the collected liquid.It enables you to reclaim expensive lubricating oil and lead to longer service life of the vacuum system.You can find these filters for vacuum pumps having flow spanning from 3-850 cfm.

Oil Filters

Vacuum pump oil filters are specialized filters designed to remove contaminants from the oil circulating within vacuum pump systems. These filters help maintain the cleanliness of the oil, ensuring efficient pump operation and extending the pump's lifespan. They typically consist of a housing with a filter element or cartridge made of materials that can capture and retain small particles. Regular maintenance and replacement of the filter element are important to ensure optimal performance and prevent clogging.

Vacuum Feeder Filter Element

The filter element of the vacuum feeder is to filter some impurities generated during the conveying and feeding process of the material, helping the material to reach a clean level before conveying. Generally, the material will pass through the filter element when it enters the hopper through the suction port. To filter the material, he can effectively help the manufacturer to filter the material to help it achieve some very good results. When filtering the material, the vacuum feeder can filter out all the dust and impurities in it, but The internal diameter of the filter element we choose is related to it, which affects the filtering effect.

Which are the Main components of Vacuum Pump Filter?

A vacuum pump filter assembly is made of the following key parts:

1.Filter housing;

Vacuum filter housing is a component that encloses and protects the filter element within a vacuum pump system, ensuring efficient filtration and preventing contaminants from entering the pump.

2.Filter element;

Which captures the particulate matter in the case of inlet filter sand oil mist for exhaust filters.

3.Drain port;

Usually positioned at the bottom of the filter and helps in removing any collected oils.

4.Filter Inlet;

Which is attached to the exhaust of the vacuum pump (exhaust filter or allows in air into the vacuum pump (inlet filter )

5.Filter outlet;

Which is connected to the vacuum pump inlet (intake filter) or exit for gas stream from vacuum pump (exhaust filter)

6.Entrainment separator pad

 In the case of multiple elements and helps to minimize chances of oil carryover.

What should you consider when choosing Vacuum Pump Outlet Filter?

There are several factors to consider when selecting a vacuum pump exhaust filter.

Let's look at the main issues to consider to make sure you choose the right vacuum pump outlet filter for your applications.

Low Maintenance 

A filter system that needs frequent replacement of paper filter needs to be avoided since the paper will get filthy very fast.

Moreover, you should not buy a vacuum pump filter that needs a lot of regular maintenance.

Though a filter system that needs minimal maintenance may be costly, the hassle and time saved throughout its life is worth the cost.


It is essential to establish beforehand the oil mist volume that you will be required to filter to maintain a safe environment.

For example, not all vacuum pump exhaust filters permit the same quantity of gas to pass through during the process of filtering.

Yet, you should not exceed the limits of your vacuum pump filter.

Therefore, to choose the right filter system for your applications, you need to go for one that permits for at minimum three times the working capacity required.

Extra Features 

Apart from choosing a vacuum pump filter that removes oil mist, you need to look for one that equally eliminates other hazardous contaminants and chemicals.

What are the uses of Vacuum Pump Filter?

Vacuum pump filters, particularly inlet filters are made to inhibit particulate matter and dirt from getting into or exiting the vacuum pump and fouling the parts of the vacuum systems.

In addition, exhaust filters prevent oil mist generated during functioning of the vacuum pump from being expelled into the environment.(Reference blog 'Precautions for Using Vacuum Pump Filter')

How do you select Vacuum Pump Filter Housing?

Most of vacuum pump filter housings are made of two materials, that is, stainless steel and aluminum.

The choice between the two materials will depend on the exhaust chemical composition.

When application involves corrosive chemicals or temperatures beyond 120°C, you should opt for stainless steel.

The size of the housing will be based on the vacuum pump's maximal free air displacement.

You should not opt for a housing having a flow rating lower than the pump as this will reduce efficiency.

What should you consider in Sizing Vacuum Pump Filter?

There are a number of factors to consider when sizing a vacuum pump filter.

Let's look at some of the main considerations when sizing vacuum pump filters.

Type of Vacuum Pump 

The major types of pump include rotary screw, reciprocating, liquid ring,rotary vane and rotary piston vacuum pumps.

Every pump type generates its distinct oil discharge features and needs the right filter media size to effectively trap and remove oil aerosols.

Particle Characteristics 

Knowing the size and type of particles sieved enables you to choose the correct micron size for the vacuum pump filter.

For instance, surface or pond water has large organic matter, like leaves and algae, whereas well water has inorganic debris, like sand.

Generally, inorganic matter will need a smaller-sized filter element to capture the sand and residue that would pass across larger-sized types.

Water is just an example, you can as well filter viscous fluids, like paint, paper coatings and honey among others.

 Maximum Operating Flow 

Flow rate is also an important factor to consider when sizing your vacuum pump filter.

For instance, a 2" filter that permits a flow of 100 gpm will not be suitable for a vacuum system working at 150 gpm.

You should choose a filter size having an operating flow greater than that of your application.

Minimum and Maximum Pressure of Operation 

Each filter has a maximum operating pressure rating.

Therefore, it is crucial to ensure a precise measurement of maximal pressure when you are sizing and choosing a vacuum pump filter.

Though minimum pressure of operation is not a necessity for all filter types, it is essential when utilizing automatic, self-cleaning filter system.

You must maintain minimum operating pressure when you engage the flushing mechanism of the filter.

Pressure Drop 

There are various factors that influence pressure drop, like viscosity, flow rate contaminants present, and filter media.

Since the size of filter element contributes to pressure drop, it is also an essential consideration when sizing your vacuum pump filter.

Pressure differential increases as the filtered residues reduce the surface area of the filter.

The desired fluid flow across the filter will be affected once it reaches a point where the pressure to surpass the pressure drop is too great.

The loading of the particulate matter and the surface area of the filter will dictate the frequency required to empty the filter element.

A small-sized filter will result in very high pressure drop, this will lead to frequent production downtime and may reduce the life span of the vacuum system.

Air Velocity 

Air velocity as well determines how you size your filter media. Maintaining the correct air-to-media ratio is important for efficient filtration process.

How does Vacuum Pump Exhaust Filter compare to Oil Mist Eliminator?

Often, people prefer to use oil mist eliminator instead of vacuum pump exhaust filter.

However, the two terms can be used interchangeable to refer to the same device.

Oil mist eliminators are model led to capture oil mist or vapor which leaves the vacuum pump when you start it.

During prolonged functioning or when you utilize the gas ballast valve to out gas or purge oil of the vacuum pump.

During the initial launch or when you open the gas ballast valve of the vacuum pump, you will easily observe the oil mist as a fine mist that gets released into the work environment.

The oil mist comprises not only of hydrocarbons but also has numerous other semi-volatile and volatile organic compounds that were contained in the lubricant.

The oil mist eliminator is devised to capture this plume of oil vapor and drain it back to the pump.

Why should you Filter Exhaust from Vacuum Pump?

The main benefits of installing vacuum pump exhaust filter comprise of:

1.Emit Clean Air into the Environment

A vacuum pump will release visible oil mist and smoke into the air.But fitting an oil mist eliminator will remove 99.9 percent of the smoke and oil mist from the exhaust fumes of the vacuum pump.This will inhibit buildup of oil in the ambient air that could as in turn lead to health hazards.

Obviously, it will violate your country's environment and occupational safety and health regulations.

2.Remove Oil in Pipes and Duct work

When a vacuum pump emits oily air, the contaminants get circulated throughout the vacuum system via the duct work and connecting pipes.This can result in dirty inlet air for other devices such as packaging machines,compressors, etc.

3.Recover Costly Lubricating Oils

Installing a vacuum pump exhaust filter can enable you recover high-cost lubricating oils and recirculate the filtered oil to the pump.Doing this reduces the general costs of maintenance.

Are there Disadvantages of using Vacuum Pump Filter?

Absolutely, there are negligible disadvantages of vacuum pump filter considering their overall benefits to your vacuum system.

Requires high initial capital and operating cost. The filter media (high-collapse kind) and housings should be designed to sustain peak system pressure.

The suction force may force fine particles past the pores of the filter element, and probably lead to contamination of the successive equipment and work environment air.

Difficult to clean particularly as needed for food grade uses.

Vacuum filter is most suitable for?

Vacuum pump filter is most suitable for applications where you need to ensure the cleanliness and efficiency of the vacuum pump operation. It is commonly used in various industries, including:

●Electric Power

●Chemical industry

●Pulp & Paper industry

●Mining, pharmaceutical

●Plastic industry

●Medical industry

●Environmental industry

●Food & Beverage

●Packaging industry

What is Multi-stage FiltrationSystem?

These are filter systems that have layered filters or two or more stages to gradually eliminate particulate matter and oil mist.The first filtration stage could be made up an oil mist eliminator.

While the second filter may comprise of a replaceable charcoal trap to eliminate volatile organic substances from the vacuum system.Multi-stage filtration systems help in filtering out particulates and corrosive fumes that can foul the vacuum pump system.This in turn extends the maintenance cycles and minimizes downtime.These systems guarantee an almost total filtration of the through-flow, with a variety of filter elements available for various fields of application.

How efficient is Vacuum Pump Filter System?

Vacuum pump filter element design enables it to have an efficiency of up to99.999% on .2 micron diameter particulates.Most of them are rated at 5ppm at 60 Tor maximal carryover.

When should you Replace Vacuum Pump Filter?

The only service commonly needed of vacuum pump filter is the periodic substitution of the filter element.

You should carry out this replacement once annually under normal conditions, unless you are purging corrosive or acid materials into the vacuum pump.

Since the filter element is commonly manufactured from paper composite,the acid or corrosive chemicals can make it to speedily disintegrate.

In this case, you will be required to replace vacuum filter more often.

Replacing the filter is a very straightforward process, you simply unbolt the two chambers of the vacuum pump filter housing and substitute the filter element using a new one.

What is the Purpose of Vacuum Filtration?

Vacuum filtration is the standard method employed in the separation of solid-liquid mixture when the objective is to keep the solid.

Also known as suction filtration, this technique is relatively quicker than gravity filtration, usually requiring less than a minute.

Vacuum filtration is more effective in eliminating liquid residues, resulting in a purer solid.

This is particularly crucial in crystallization, since the liquid may have soluble contaminants that have the potential of adsorbing back onto the surface of the solid after evaporation of the solvent.

Clearly, vacuum pump filter plays an integral role in most industrial setups.

lt not only ensures efficiency, but guarantees the reliability of the entire process.

With the information in this guide, l hope you can choose a suitable vacuum pump filter for your specific applications.
