30 HP Rotary Screw 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.

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.

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.
