Oil Free Air Compressor

Oil-free air compressors deliver compressed air without lubricating oil in the compression chamber. They produce clean, uncontaminated air output. Furthermore, they suit breathing air filling, pharmaceutical manufacturing, food processing, electronics assembly, and laboratory instrument supply where oil contamination would damage products or personnel.

Oil-free compression uses three main technologies. Scroll compressors use two interlocking spiral elements — one fixed and one orbiting. They compress air progressively without metal-to-metal contact. This produces quiet operation at 40 to 60 dB(A) with vibration-free output. Furthermore, reciprocating oil-free piston compressors use PTFE-coated piston seals in the cylinder bore. They reach pressures of 10 to 40 bar on medical and industrial models. Rotary screw oil-free compressors inject water for sealing and cooling. As a result, they produce ISO 8573-1 Class 0 oil-free air at flow rates from 1 to over 100 m³/min.

ISO 8573-1 Class 0 certification confirms zero detectable oil in compressed air output. This is mandatory for pharmaceutical GMP manufacturing, food contact air applications, and breathing air filling systems. Additionally, integrated air treatment trains include refrigeration dryers, desiccant dryers, and coalescing filters. These remove moisture, dust, and trace contaminants to meet each application’s specific air quality class.

Tank capacities range from 8 liters on compact portable models to 500 liters on industrial fixed installations. Motor power covers 0.5kW on small dental units to 75kW on large production systems. Pressure ratings span 8 bar on standard compressors to 40 bar on high-pressure medical and diving air applications. Moreover, portable oil-free models weigh under 20kg — directly suitable for field medical unit deployment across Pakistan’s remote northern terrain.

These compressors serve Pakistan’s pharmaceutical plants in Karachi and Lahore, CMH hospital medical air systems, dental clinics, food packaging facilities, electronics cleanrooms, and laboratory instrument air supply programs.

Tactical Supply Pakistan supplies oil-free air compressors for pharmaceutical manufacturing, medical air systems, food processing, and laboratory air procurement across Pakistan.
