Pharmaceutical/Medical Air Compressors

Why does the pharmaceutical or medical industry need Class 0 oil-free clean, dry compressed air?

Such as tablets, pills, capsules, ointments, creams, gels and syrups. Compressed air comes into contact at almost every step of the production process: mixing, pelletizing, drying, pressing, coating and packaging. Containers such as bottles, tubes and jars should also be washed and dried before filling.

Typical Applications for Pharmaceutical Compressor

Common applications for pharmaceutical compressors?


PVC material blow molding blister packaging machine

For capsule and flatbed printers

Medical Blow Molding Machine

for automatic manga machines

3D Packaging of Transparent Films

For automatic filling and sealing machine


After cleaning with compressed air, plastic containers, blow bottles, and ampoules are manufactured in a sterile area.
Bottles, tubes, vials, and various types of packaging need to be washed and dried before use. These packages are in direct contact with the product, so the air must be arid and oil-free.

For example, ultrasonic bottle washing machines such as 1-20ml ampoules, 2-100ml syringes, molded bottles, oral liquid bottles, etc., provide power to remove impurities in the bottles altogether.

Smashing, grind and micronizing powders Used in the jet mills, traditional Chinese medicine mills, rotary tablet press, capsule polishing machines, etc., to remove dust and impurities in time.

Liquid preparation filling machine.

It is used in a capsule filling machine to discharge the filled capsules in time to prevent the filling process from being interrupted due to untimely discharge.

Needle encapsulation, powder needle filling, and other demanding applications,

The spraying device of the coating machine. Compressed air powers the gun to spray liquids or adhesives, as well as remove dust.

For one-step granulator (also known as boiling granulator, fluidized spray granulator, fluidized bed granulator, etc.)

It is used in a high-speed mixing granulator to provide a sealed environment and a certain power for the process so that the material can be mixed evenly, and it can also provide more power for the unloading and feeding of the material.

Active Pharmaceutical Ingredients(APIS)

Used for slagging in extraction and concentration tanks during extraction.
Seedling fermentation tank dilution tank, vaccine semi-finished product preparation, raw material mixing, liquid dispensing.

Herbal sterilization equipment provides a closed environment for better sterilization.


For pneumatic conveying during manufacturing.
For control valve, sorting, polishing, etc.

Wastewater treatment The water used in the manufacturing process needs to be treated in castings that contaminate the product.

Typical Applications of Medical Compressors

Some common applications include:

hospital oxygen generator
Breathing equipment, oxygen concentrators, nebulizers
Dental beds/seats/chairs, dental milling machines
Surgical Instruments
blood analyzer
Chiropractic and Physical Therapy Forms
Endoscopic equipment
ENT Air/Vacuum Aspirator
Evacuation/sealing/welding of bags/bottles (blood)

Quality Requirements for Pharmaceutical/Medical Compressor

In the pharmaceutical industry, compressed air should remove contaminants before use. Common contaminants are solid particles, water vapor and moisture, and oil vapor. Mainly used for atmospheric pressure, oil-filled air compressors lubricating oil, pipelines, gas storage tanks, distribution, etc.

When compressed air is directly related to pharmaceuticals or medical products, we must guarantee purity and cleanliness to prevent contamination. Specifically, what we should do is as follows:



Remove the moisture

As we know, moisture is good for microorganisms and fungus growth. If there is moisture inside the compressed air pipes, it is easy to be blown to the products, packaging, or containers. So we need to use dryers to ensure the required dew point. Generally, for direct contact compressed air, the dew point should be -40℃ and use a desiccant air dryer, and for low-risk non-contact compressed air, the dew point can be 3℃ and use a refrigeration air dryer.


Remove Oil

There is oil in the atmosphere, so even if you choose a 100% oil-free air compressor, there is still oil vapor in the compressed air, so you should use a filter.

In general, for compressed air in direct contact, oil-free air compressors must be used. Ensures Class 0 100% high purity oil-free compressed air, eliminating the health risks of rejection risks associated with oil contamination. For low-risk non-contact compressed air, we can use more economical oil lubricated air compressors, but it is best to use a filter to ensure 0.003ppm oil content.


Remove Particles

The atmosphere contains solid particles or dust that can cause contamination if it comes into contact with food. Other contaminants can come from the internal mechanisms of the air compressor system. We also need filters to ensure that the particle content does not exceed 0.01μm.


Common Equipment for the Pharmaceutical/Medical Applications

  • For compressed air in direct contact in the production line, we recommend a 100% oil-free air compressor with desiccant air dryer and filter, and food-grade stainless steel.
  • For non-contact, low-risk compressed air for production lines, oil-lubricated air compressors with refrigerated air dryers and filters can be an option if you are on a budget, but in the long run, oil-free air compressors can not only produce high- Premium oil-free clean air with lower maintenance and energy costs.
