Certified Oil Free Scroll Air Compressors Manufacturer

Kolkata industries in pharmaceuticals, healthcare, food processing, laboratories, breweries, and electronics manufacturing cannot risk oil contamination in compressed air systems. Even trace oil affects product quality, damages sensitive equipment, and creates compliance problems in controlled production and medical environments.

Frank Compressors manufactures oil free scroll air compressors in Coimbatore under ISO certified standards and supplies directly across Kolkata and West Bengal. Built on fourth generation scroll compressor technology, these systems deliver 100% oil-free compressed air with low operating noise from 64 dB to 70 dB, compact installation, energy-efficient performance, and models ranging from 3 HP to 30 HP with tank-mounted and base-mounted configurations.

Why Kolkata Industries
Use Oil Free
Scroll Air Compressors

Kolkata’s pharma plants, hospitals, food processors, laboratories, breweries, and electronics manufacturers operate processes where even minor oil contamination affects production quality and regulatory compliance. Oil-injected compressors carry contamination risk even after filtration, while oil free scroll compressors eliminate the problem directly at the compression stage.

Zero Oil Contamination

The scroll mechanism compresses air without allowing oil into the chamber, indicating there's no need for oil separators or filtration systems downstream.

Quieter Than Conventional Compressors

A complete compression cycle is achieved in 2.5 scroll turns, resulting in pulse-free air flow and operating noise levels in the range of 64 dB and 70 dB.

Fewer Moving Parts and Lower Maintenance

The mechanism uses only one moving component with no pistons, valves, connecting rods, or timing gears requiring regular replacement.

Energy Efficient Operation

High volumetric efficiency lowers power consumption per unit of compressed air compared to oil-free piston compressor systems.

How an Oil Free Scroll Air Compressor Works?

01

Air Intake

Inlet filter removes dust and particulates before air enters the scroll compression stage for oil-free operation.

02

Scroll Compression

One scroll remains fixed while the second scroll orbits, progressively reducing chamber volume toward the centre outlet.

03

Non-Contact Operation

Scroll discs never touch directly during compression, eliminating oil lubrication and reducing compression surface wear.

04

Discharge

Compressed air exits through the centre discharge port after a 2.5-turn compression cycle with pulse-free airflow.

05

Delivery

Clean oil-free compressed air is stored in the receiver tank and supplied without downstream oil filtration requirements.
