Rotary Screw Compressors
Continuous-duty units for multi-shift production. This range runs several models deep, so the full spec table — not a wall of cards — is the fastest way to compare.

Sizing & sales FAQs
What is the difference between a piston (reciprocating) and a screw air compressor?
A piston compressor uses pistons moving inside cylinders to compress air in pulses — it is simpler, cheaper to buy and repair, and well suited to workshops or intermittent use of an hour or two a day. A screw compressor uses two meshing rotors to compress air continuously and smoothly — it costs more upfront but handles continuous, high-volume use with less vibration, lower noise and typically a longer service life. Factories running production lines or paint booths for a full shift usually need a screw compressor; a small garage or fabrication workshop is often better served by a piston unit.
What size or type of compressor do I need for my workshop or factory?
Sizing depends on your total air demand (CFM) at the pressure your tools or process need, plus how continuously the air is used. As a rough starting point: small workshops running one or two pneumatic tools intermittently are usually fine with a 1–5 HP piston compressor; CNC lines, paint booths, pneumatic assembly tools or continuous-process factories typically need a 10 HP-plus screw compressor with a properly sized receiver tank. We visit or ask a few questions about your equipment and usage pattern to recommend a size rather than guessing from HP alone — undersizing causes constant cycling and early wear, and oversizing wastes power.
Do you take my old compressor in exchange when I buy a new one?
This is evaluated case by case depending on the condition, brand and resale value of the old unit. Mention it when you enquire about a new compressor and we will inspect it and let you know if an exchange or buy-back is possible.
What do I need to prepare before installing a new air compressor?
In general: a level, vibration-resistant foundation, adequate ventilation and clearance for heat dissipation (especially for screw compressors), a dedicated electrical line sized for the motor with proper starter/VFD protection, and a piping layout that avoids unnecessary bends and long runs which cause pressure drop. For processes needing dry air (paint booths, pneumatic instrumentation, electronics-adjacent work) you will also need a moisture separator and dryer sized to your flow rate. We advise on this during the site visit before delivery so there are no surprises on installation day.
