Product Identity

The SPEEDAIRE air inlet 4320309G is a new replacement component designed for compatible air compressor systems. It serves technicians and maintenance teams who need a direct-fit inlet for specific Speedaire units. Buyers requiring a different connection type or a unit for an incompatible brand should look elsewhere.

Thermals, Noise and Power

This inlet is a passive part with no motor, fan or electrical draw, so it adds no heat, noise or power consumption during normal compressor operation. The only regulatory note is a California Proposition 65 warning that the product contains a chemical known to cause cancer and birth defects or other reproductive harm.

Sustained Load Behaviour

Under continuous compressor cycling the inlet maintains airflow without active cooling or moving parts to degrade. Its performance depends entirely on the host compressor’s duty cycle and filtration setup. Orders of $75 or more qualify for free shipping from the supplier.

Questions about this item

How do I install the SPEEDAIRE 4320309G air inlet and what step is most often missed?

Thread the inlet into the compressor intake port using the correct pipe sealant, then tighten to the manufacturer's torque value; the step most often missed is applying fresh sealant on clean threads to prevent air leaks.

What maintenance or replacement will the SPEEDAIRE 4320309G air inlet need over time?

Inspect the inlet filter screen regularly for debris and clean or replace it when airflow drops; the inlet body itself only needs replacement if the threads are damaged or the housing cracks.

What limit appears first on the SPEEDAIRE 4320309G air inlet during sustained compressor operation?

The inlet screen clogs with dust and oil mist before any structural limit is reached, reducing airflow and forcing the pump to work harder.
