10 HP Cast Iron Duplex Air Compressor with 120 Gal Receiver for Single Phase Shops

One compressor means one point of failure. When it quits mid-job, every air tool in the shop goes quiet.

The BelAire 4112D is a 10 HP duplex compressor with two cast iron pumps and motors on a 120 gal air receiver. It provides 36 cfm on 208-230V single phase power.

Why Choose the 4112D

36 cfm on single phase power, with a backup pump built in.

  • 36 cfm on single phase — no three-phase service needed
  • Built-in backup — if one pump fails, the other keeps running
  • Automatic alternation — equal run time on both pumps and motors
  • 120 gal air receiver — 175 psi max pressure

Made For

Built for shops that can't afford to lose air.

  • Auto repair shops
  • Tire shops
  • Body and collision shops
  • Fleet maintenance garages
  • Shops on single-phase power that need backup air

Features

  • 10 HP duplex — two pumps and two motors
  • 36 cfm — on single phase power
  • 175 psi max pressure — headroom for tire and impact work
  • 120 gal air receiver — shared by both pumps
  • Cast iron pumps — built for shop duty
  • Automatic alternator — balances run time between pumps
  • 208-230V single phase — runs on standard shop power

Second Pump When You Need It

The first pump handles normal demand. If it can't keep up, the second pump kicks in automatically.

The alternator switches which pump leads, so both pumps and motors get equal run time and wear.

A Backup Built Into the Unit

If one pump fails, the other is still fully functional. The shop keeps working on air while the down pump is serviced.

That makes the 4112D a strong fit for a shop on single phase power that can't stop for a compressor repair.

The Right Air Compressor for Your Shop

The 4112D gives you 10 HP of duplex air, 36 cfm, a 120 gal receiver and a built-in backup on single phase power.
