Within Compressors, Belt Drive Compressor covers the compressors that couple the electric motor to the air pump via a belt-and-pulley drive — the workhorse design for sustained, continuous-duty workshop air supply. Belt-drive compressors run at lower pump RPM than direct-drive equivalents, deliver higher CFM at lower noise levels, and are designed for high-cycle workshop and fleet-bay use. Parts For Machines supplies belt-drive compressors for trade and professional applications.
Belt-drive compressors are sized by motor power, tank capacity, and CFM output. Typical trade-grade configurations: 3-4 hp single-phase motors driving 100-150 litre vertical tanks delivering 12-18 CFM at 8 bar — suitable for single-bay workshop and fleet applications; 5-7.5 hp single- or three-phase motors driving 200-270 litre tanks delivering 20-30 CFM — suitable for multi-bay workshops and continuous-duty applications; 10+ hp three-phase compressors driving 270-500 litre tanks delivering 35+ CFM — industrial and high-throughput applications. Parts For Machines is an Authorised Distributor and Seller of SIP across belt-drive compressors.
SIP is the dominant brand at Parts For Machines, with the deepest range across single-phase and three-phase configurations and the workshop standards in the trade-grade segment. Nuair extends the range with compressor-pump options and complete machines used in industrial applications. Sealey, Draper, and Clarke provide additional choice across the smaller tank-and-output configurations. Product pages list motor power (in hp or kW), input voltage and phase (single-phase 230V or three-phase 400V), tank capacity (in litres), CFM output (at the rated working pressure — typically 8 bar / 116 PSI), maximum pressure rating, and pump duty cycle (continuous-duty or 50%-duty intermittent).
The pump and motor sizes determine the cooling and longevity at sustained use. Trade pricing on multi-unit and workshop fit-out orders is available; contact the team via WhatsApp 07754288583 for a quote on full-bay specifications. For pneumatic-tool operation guidance, see the Air Tools sub-section.
