Screw Type Compressor Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-13129
Jlab Export is a leading Screw Type Compressor Manufacturer,and suppliers in India
In a screw compressor, two meshing helical rotors trap gas between their lobes and squeeze it as each pocket shrinks on its way to the discharge end. This model is cut out from an original screw type compressor to expose all its key parts. It is belt driven, colour coded and fitted with a rotating handle for turning by hand.

Workshop Practice with the Cutaway
Students start by naming the parts they can see: the male and female rotors, the housing around them, the suction and discharge ports, the shaft and its bearings. The teacher then turns the handle slowly. The class follows one space between two lobes from the suction end to the discharge end and watches it get smaller.
For a lesson on compressor types, line this cutaway up with the Scroll Hermetic Compressor and the Reciprocating Hermetic Compressor. Both are cut and colour coded in the same way. Each student sketches how gas is trapped, compressed and pushed out in each design. Afterwards the class can watch a working compressor on the Refrigeration Test Rig and read its suction and discharge pressures.
Frequently Asked Questions
How does a screw compressor compress the gas?
Two helical rotors mesh inside a close-fitting housing. The male rotor has convex lobes and the female rotor has matching flutes. Gas fills the open pockets at the suction end, and as the rotors turn each pocket closes, shrinks and moves along until it opens to the discharge port.
How is it different from a reciprocating compressor?
A reciprocating compressor uses pistons with suction and discharge valves and delivers gas in pulses. A screw compressor has no pistons and no valve plate. The rotor lobes cover and uncover the ports themselves, so the flow is smooth and steady.
Where are screw compressors used?
Mostly in larger plants such as industrial refrigeration, water chillers and factory compressed air systems, where long running hours and steady flow suit a rotary design. Household refrigerators and room air conditioners normally use reciprocating, rotary or scroll compressors instead.
Why is oil injected into many screw compressors?
In an oil-injected screw compressor, oil sprayed into the housing seals the small gaps between the rotors and the casing. It also lubricates the rotors and carries away much of the heat of compression. An oil separator then takes it back out of the discharge gas.
How is the output of a screw compressor reduced?
Most refrigeration screw compressors have a slide valve along the rotors. Moving it opens a path that returns part of the trapped gas to suction before compression starts, so less gas is delivered. Some machines vary the motor speed instead.
