Screw Air Compressors with Permanent Magnet motor and VFD

Our Rotary Screw Air Compressor available in Standard Fix Models up to 335 HP and VFD Models up to 100 HP. We use PM Motor with our VFD Models, which decrease the energy consumption substantially to save even more energy as well as money.

Why Comptech Screw Air Compressor?

Super premium efficiency IE4 Pm Motor

Vibration free quieter operation

Designed for hot indian climate

Service friendly design

Direct drive with low rpm

Advance PLC for easy operation

Lowest oil carry over

Lowest life cycle cost


Energy Saving 1:1 Direct Drive

1:1 Direct drive reduces number of components needed in gear drive or Belt Drive, increasing reliability and durability through elimination of wear & transmission loss.

Benefits: Low maintenance & no transmission loss


Air & Oil Cooler

Based on the Hot Climate of India, we provide Big size, high efficient Air & Oil Cooler which increases the durability of the Compressor.

Benefits: Better Cooling & better compressor life.

Seamless Pipelines

We use Seamless, long life Pipelines with best quality connections.

Benefits: Elimination of Oil Leakages.


Advanced microprocessor based control system with features such as online pressure, temperature and current measurement, safety settings, online maintenance indications. It also has a unique fan control system which eliminates use of thermostats in the compressor.

Benefits: Easy and Simple operation.

High Capacity Dual Air Filtration

Big Size, High efficient , dual filtering stage suction Air Filter for Dusty Environment of India with pre-filters, which reduces the intake of dust into the compressor.

Benefits: Lowest dust intake into the compressors.

Oil Seperation System

Two stage oil seperation system in which Oil is initially separated by Centrifugal force and minimal oil remains are then separated by separator element.

Benefits: Lowest Oil Carryover.

Best in Class Screw Profile

We use Premium quality Airend with high precision rotors, which operate at low RPM to provides best efficiency.

Benefits: High Efficiency Air Flow & longer life.

Control Panel

Control Panel / starter has been put in the cold zone which ensure long life operation. Switchgears and other electricals are also made of Siemens or standard quality.

Benefits: Lesser chances of electrical faults and breakdowns.

Typical Air Supply System

Air boosters take pre-compressed air from an existing network (your plant air system) or from a low-pressure compressor and increase it to the required higher pressure. A CompTech Air Booster is a specially designed reciprocating compressor that accepts elevated inlet pressures of 10 kg/cm² and boosts that pressure up as far as 40 kg/cm².

A revolution in energy saving VFD (Variable Frequency Drive) with PM Motor

With the motive to reduce the Energy cost in our Air Compressors, we now introduce Energy saving Permanent Magnet Motors with our VFD models which decrease the Energy consumption substantially to save even more energy as well as money.

Power Saving with VSD

Low Starting Current

Constant Outlet Pressure

Low Maintenance

High Savings Under Fluctuating Requirement

VSD ensures there will be no high current peak at the startup, as current increases gradually, which eliminates the use of heavy equipments to withstand the peaks.

Because of the narrow pressure band, the consumption at the peaks are omitted in comparison with Star Delta controls. This reduces energy consumption and provides a stable pressure.

Due to VSD, the average RPM of the compressor also reduces, which means lesser wear & tear and results into less maintenance

During Low requirement, VSD reduces the speed of motor resulting in low energy consumption. The compressor will consume just the energy for the required air it produces.

Why PM Motor?

  • Interior PM (IPM) Motor Efficiency upto 94.5%, which outperforms Ie3 efficiency level
  • On Average 20% Lower specific Energy Requirement than the current VSD models
  • On top of energy savings, Free Air Delivery (FAD) increase up to 12% over the range
  • Compact small in size IPM motor has no bearings which means no wearing parts, no maintenance on motor side and no gears or belts, leading to a Transmission Efficiency of 100%

Power Saving with VFD


Replaced my existing compressor with Comptech VFD+ Series, which gave me around 25% savings on my Electricity Bill. Amazing Product.
