Heavy-Duty Oil Free Screw Compressors in Kolkata

Kolkata’s pharma plants, food processors, textile mills, electronics manufacturers, and hospitals cannot risk oil contamination anywhere in the compressed air line. Even minor oil carryover affects product quality, damages sensitive equipment, and creates compliance issues in GMP, ISO 8573, and food-grade production environments.

Frank Compressors manufactures oil free screw air compressors in Coimbatore and supplies directly across Kolkata and West Bengal in capacities from 10 HP to 75 HP. These two-stage VSD compressors use specialised rotor coatings for oil-free compression, operate between 57 dB and 67 dB, and deliver stable output across 7 bar, 8.5 bar, and 10 bar pressure settings with lower energy consumption and reduced operating cost.

Why Kolkata Industries
Choose Oil Free
Screw Air Compressors

Pharma units, food processing plants, textile mills, hospitals, and electronics manufacturers across Kolkata need compressed air that remains completely free from oil contamination during production. Oil-injected systems still carry downstream contamination risk, while oil free screw compressors remove that problem directly at the compression stage.

Zero Oil in the Compression Chamber

Specially treated rotors compress air without oil contact, keeping compressed air free from oil vapour and contamination risk.

VSD Technology for Lower Power Consumption

Variable speed drive adjusts motor speed according to air demand, reducing electricity usage during lower production loads.

Low Noise for Production Environments

Operating noise between 57 dB and 67 dB suits cleanrooms, textile floors, hospitals, and indoor process facilities.

How an Oil Free Screw Air Compressor Works?

01

Oil-Free Delivery

Specialised rotor coatings allow compression without oil entering the compressed air stream at any stage.

02

Air Intake

Inlet filter removes dust and particulates before air enters the first-stage compression chamber.

03

First Stage Compression

Male and female rotors compress incoming air progressively as cavity volume reduces toward the discharge port.

04

Intercooling

Intercooler lowers air temperature before second-stage compression to improve efficiency and reduce operating load.

05

Second Stage Compression

Pre-compressed air enters the second stage where pressure increases to the required outlet level.

06

Pressure Control & Delivery

VSD controller adjusts motor speed continuously to maintain stable outlet pressure during operation.

FAQ

FAQs on Oil Free Screw Air Compressors in Kolkata

Because downstream filters are not enough in sensitive production. Pharma plants want compressed air without oil risk from the start itself.

Yes. Even minor oil carryover can affect packaging quality, product safety, and compliance during food processing operation.

Yes. Textile units use them to avoid oil stains, thread damage, and moisture-related defects during continuous production shifts.

Compression happens progressively in two stages, so outlet temperature stays lower and power consumption reduces during operation.

Yes. Laser cutting systems need clean compressed air because oil contamination affects cut finish and damages laser lenses.

Not necessarily. VSD technology adjusts motor speed automatically according to real-time air demand inside the plant.

Yes. Operating noise remains between 57 dB and 67 dB, making them suitable for indoor industrial environments.

Pharma, food processing, healthcare, electronics, textile, printing, and precision manufacturing industries use them regularly.

No. Compression itself happens without oil contact, so there is no downstream oil carryover to remove later.

Air demand in CFM, pressure requirement, production load, and running hours are checked before selecting the right model.

Yes. Installation, testing, commissioning, and startup support are provided across Kolkata and nearby industrial locations.

Yes. Existing air receivers, pipelines, pressure drops, and load conditions are checked before final integration.

Mostly routine inspection, filter replacement, and monitoring of operating parameters. Service intervals remain comparatively lower.

Yes. Genuine spare parts and trained service teams are available across Kolkata and West Bengal for faster response times.
