What Is a Pneumatic Oil Filter Machine?

Pneumatic Oil Filter, also known as Air Pressure Oil Filter, is a machine that uses air pressure to achieve high-efficiency filtration. It uses the thrust of compressed air to push freshly extracted oil through multiple layers of fine filter cloth or filter paper (freely combinable). Users can use the appropriate number of filter layers according to the concentration and type of oil to be filtered to achieve the purpose of precision filtration.
Unlike plate and frame filter press or centrifugal filtration methods, pneumatic oil filter machines apply constant air pressure to quickly separate suspended particles, seed residues, moisture and colloids in crude oil. It is very popular in rural cooperatives, family oil mills, small and medium-sized oil mills and self-employed edible oil filtration processing.
This type of filter is particularly suitable for producers who process 50-1000 kg of oil per day and want to achieve the following goals:

Fast filtration speed
High oil clarity
Low residual impurities
Stable performance and minimal human intervention

From peanut oil to sunflower oil and sesame oil, Pneumatic Oil Filter not only improves the edible quality of crude oil, but also meets the needs of local market sales. For farms and oil mills that want to upgrade traditional filtration methods, pneumatic oil filter is one of the modern professional filtration solutions.

How does the Edible Oil Pneumatic Oil Filter work?

At the heart of the pneumatic edible oil filter is the intelligent integration of mechanical structure and pneumatic pressure control. The core components include: sealed oil drum with filter cloth separation layer, air compressor/pneumatic pump, oil outlet valve, safety valve, and pressure gauge.
Instead of waiting for gravity to slowly trickle the oil through the filter, we use the pressure of high-pressure gas to force the oil through multiple layers of filter cloth. Quickly filter out suspended solids, sludge, etc. in the oil of 5-20 microns to achieve the purpose of clarification and decolorization.
The filtration process is as follows:

The crude oil extracted from the seeds by the screw oil press / hydraulic oil press is fed into the filter tank.
The connected air compressor creates pressure in the chamber, forcing the oil to pass quickly and evenly through each layer of the filter.
The solid particles in the crude oil (seed shells, gums, fibers, dirt, etc.) are blocked on the surface of the filter cloth to form a filter residue.
The purified oil flows out through the outlet valve, ready for bottling, sale or further refining.

The best part? No heating and no chemicals. This method of edible oil filtration not only shortens processing time, but also avoids the loss of original ecological flavor due to oxidation or overheating.

Air Pressure Oil Filter Machine Usage Process.

As any oil miller knows, freshly squeezed oil is rarely clean—it’s filled with tiny seeds, water, and other impurities that we don’t want in our final product. This is where the pneumatic oil filter comes in handy. The name sounds like it requires a bit of technical skills to use. But everyone who has seen it work says, “Haha, this is so easy.” The normal use process is nothing more than: connect the oil pipe → start the air pump → automatically pressurize → discharge the clean oil from the oil outlet.

Connect the oil pipe of the oil press to the oil inlet of the air pressure oil filter. Make sure all interfaces are tightened to avoid leakage.
Next, turn on the air pump. Create internal pressure for the oil filter tank.
Once the internal air pressure increases (don’t worry, we can monitor it in real time through the built-in pressure gauge), the crude oil will be pushed through the filter cloth.
After a while, open the oil drain valve at the bottom and you will see clean oil flowing out. Just put the container below, that’s it!

The whole process is fast, smooth and efficient. Perfect for farms, rural oil mills or any entrepreneur running a small edible oil production business. Even for first-time novices, the operation is very simple and can be mastered after just a few uses.

Features of Edible Oil Pressure Oil Filter.

When we spoke to small oil mill owners, rural entrepreneurs, and farmers who are expanding their edible oil production, one thing they mentioned again and again was the desire for clean, market-ready oil without slowing down production. That’s why various small and medium-sized commercial Oil Filter Machines have become a popular choice for rural oil mills and small oil mills.

Pneumatic pressure oil filter is designed for continuous operation. It can be easily integrated with the screw oil press into a complete vegetable oil production line. This means that while the screw oil press is pressing the oil seeds & nuts, the filter is already working synchronously. The edible oil that comes out is clear and can be directly cooled and bottled. How wonderful!
Its compact design is another major advantage, especially when the space in the oil press workshop is limited. GQ-Agri’s Pneumatic Oil Filter has a small footprint, a simple structure, and reliable sealing performance.
In addition, Air Pressure Oil Filter is suitable for processing a variety of oils – from peanut oil, sunflower oil, sesame oil, rapeseed oil to palm kernel oil. For companies that need to process a variety of raw materials, it can reduce the investment in purchasing multiple filtration equipment.
Compared to plate and frame oil filters, Air Pressure Oil Filter avoids the problems of complicated operation, high workload, and oil leakage caused by installation errors. Compared with centrifugal oil filters, it eliminates the need for hydration treatment and is simple to operate.

Of course, no machine is perfect. Air pressure oil filters require an air compressor and regular cleaning of the filter cloth. For some very large industrial plants, plate and frame filters or refiners may be more suitable. Click here for detailed oil plant oil filter types and selection guides. Be sure to balance speed, quality and cost in accordance with actual production requirements.

Pneumatic oil filter can be matched with the recommended models.

I believe that everyone who sees this is already very interested in vacuum oil filters. But when building a reliable small and medium-sized edible oil production line, it is rare for a single machine to operate alone. In my experience, the benefits of the oil mill can only be maximized when the pneumatic oil filter works in conjunction with supporting equipment – both in terms of finished oil quality and oil extraction efficiency. This requires decision makers to envision the entire oil process: from raw seeds to roasting, pressing, filtering, and finally to bottling clear, marketable edible oil.
I have selected some combined oil pressing equipment that can be used with Air Pressure Oil Filter:

Drum Roasting Machine:

Precisely controlled roasting processes can increase the oil yield of oilseeds and fully release the unique and rich flavor of crops such as sesame oil and peanut oil. The drum seed roaster evenly heats oilseeds & nuts, roasting them to optimal moisture and temperature conditions before pressing. Want to get a manual on the best roasting temperature for crops? Contact me to send it to you.

Screw Oil Press:

This is the main equipment for hot pressing of vegetable oil in batches, and is widely used to press common raw materials such as peanuts, sunflower seeds, sesame or rapeseed. Screw presses are highly efficient at extracting oils from a wide range of oil-bearing crops, and provide a consistent crude yield. Ideal for use with your pneumatic filter for fast post-pressing purification.

Hydraulic Oil Press:

Hydraulic oil presses offer a slower but gentler pressing method that is suitable for the market demand for cold pressed oils with delicate flavors (such as sesame or walnut oils). The extracted oil usually has minimal thermal degradation, retains more nutrients, and is very suitable for the specialty or high-end edible oil market. After that, it is filtered by a pneumatic oil filter to obtain clean, clear, natural and high-quality oil.

Refinery Equipment:

Perhaps, the oil produced by your edible oil processing plant is not only sold locally, but also needs to be sold in supermarkets or exported as a brand. In that case, the oil needs to be extra shiny, and even the finest suspended particles must be removed. We can use the Refinery machine to perform secondary processing after the pneumatic oil filter to obtain an almost crystal clear oil product. At this point, the oil product reaches the highest transparency, which enables high-quality packaging and longer shelf life.

Planning the market positioning in advance and establishing the edible oil processing plant from the perspective of the production line can ensure that high-quality edible oil can be produced continuously and efficiently after opening. Pairing the pneumatic oil filter with the right upstream and downstream equipment can reduce manual operations, improve quality control, and increase production capacity.
If you are unsure which combination will best suit your production goals or marketing plans, I can help. Whether it is selecting the right screw press model, configuring dedicated auxiliary devices, or planning for future scalability, we start from the actual situation (specific raw materials, target capacity and budget) to guide you to find an effective solution.

What types of edible oil can this pneumatic filter process?

Our pneumatic oil filter is suitable for cold-pressed and hot-pressed oils from a variety of crops. For example: peanut oil, soybean oil, sunflower oil, sesame oil, rapeseed oil, palm kernel oil, cottonseed oil, mustard oil, walnut oil, camellia oil, coconut oil, corn germ oil, linseed oil, hemp seed oil and almond oil.

What is the production efficiency of Pneumatic Oil Filter?

Our standard pneumatic oil filter can process 20-120 kg of crude oil per hour, depending on the machine model and the type and viscosity of the oil. For larger-scale production or special needs, we also provide customized solutions to meet your processing capacity.

Is it suitable for continuous oil filtering during pressing?

Yes. It is designed to run online with the screw oil press for continuous filtration. You can press and filter at the same time without stopping the oil pressing line. This means faster operation, less downtime, and more consistent quality of each batch of oil.

What are the power requirements for the pneumatic system?

You need a standard power source (usually 220V or 380V) to drive the pump and control system, and an air compressor to provide a steady pressure (usually 0.6-0.8 MPa). If you already have a compressor, it will be easier to install it integrated.

How often do I need to change the filter paper or filter cloth?

Normally we recommend customers to clean the filter paper or filter cloth every 100-300 liters of oil filtered, and replace it every 500 liters of oil. The specific cleaning & replacement frequency depends on the type of oil and the impurity content. Heavier oilseeds such as sesame or palm kernel may need to be changed more frequently. The filter cloth and filter paper are standard, affordable and easy to purchase locally or from us.
