Description
-BelAire 338H4 5-HP 80-Gallon Two-Stage Air Compressor (460V 3-Phase)
The BelAire 338H4 is a professional two-stage air compressor engineered for heavy-duty industrial and commercial applications. Powered by a 5 horsepower motor operating on 460-volt Three Phase power, it delivers 18.5 cubic feet per minute at 100 PSI and 16.6 CFM at 175 PSI, with a maximum pressure of 175 PSI. This performance ensures a steady and reliable supply of compressed air for demanding pneumatic tools and equipment.
The compressor features a durable belt-driven two-stage pump with a solid cast-iron cylinder and stainless steel valves, providing consistent operation and long service life. An integrated aftercooler helps reduce moisture content and maintain optimal operating temperatures, extending pump and tool life. It comes equipped with a magnetic starter for smooth motor operation and a start-stop pressure switch for user convenience.
Air is stored in an 80-gallon horizontal ASME-certified tank, offering ample reserve capacity to reduce motor cycling and improve efficiency. Maintenance and safety features include an oil sight glass for quick checks, a fully enclosed high-flow belt guard to protect moving parts, a manual tank drain valve, and an ASME-approved safety relief valve for safe operation.
