ABAC A39B Air Compressor Pump Head

Genuine ABAC replacement pump unit for heavier-duty compressor performance

The A39B is ABAC’s larger-capacity twin-cylinder pump unit, built for compressors that need more air delivery and sustained heavy-duty output than the A29B range. It’s a direct, one-for-one swap for the original pump on compatible ABAC belt-driven machines, letting you restore full performance without replacing the whole compressor.

Product Specifications

Note: Actual air delivery (CFM/FAD), RPM, and pressure output depend on the specific ABAC compressor model the A39B is fitted to — typically in the 13.8–27.6 CFM range across the A39B PRO series. Confirm exact compatibility using your compressor’s model/serial number, or contact Adex for the technical datasheet.

Key Features

• Twin-Cylinder, Heavy-Duty Design — A robust 2-cylinder pump built to handle higher air demand than single-cylinder units, suited to workshops, garages, tyre shops, and light industrial use.
• Genuine ABAC Quality — The same proven pump unit fitted to ABAC’s original A39B compressor range, backed by ABAC’s global manufacturing reliability.
• Efficient Cooling — Die-cast aluminium cylinder heads with large cooling fins, combined with an intercooler and shroud design, keep operating temperatures down and reduce wear on valves and cylinders.
• Cast Iron Durability — Cast iron cylinder construction is built for long service life under continuous or heavy-duty operation.
• Quiet, Slow-Running Belt Drive — Reduces noise and mechanical stress compared to direct-drive pumps, for smoother, more efficient operation.
• Straightforward One-for-One Replacement — Designed as a complete drop-in swap for the original A39B unit, minimizing downtime during servicing.
• Complete Kit — Supplied with flywheel and air filter, ready to mount and connect.
• Scales With Bigger Machines — Fits the higher end of ABAC’s belt-drive lineup, suited to 3–5 HP compressors and larger tank sizes.

Frequently Asked Questions (FAQs)

1. What is the ABAC A39B pump head used for? It’s a genuine replacement pumping unit for ABAC’s larger belt-driven piston compressors, used to restore performance when the original twin-cylinder pump wears out or fails.

2. What’s the difference between the A29B and A39B pump heads? The A39B is a larger-capacity twin-cylinder unit generally paired with 3–5 HP compressors and bigger tanks, delivering higher air output than the A29B, which is suited to smaller, lighter-duty compressors.

3. Does the A39B pump head come pre-filled with oil? No. It’s supplied dry. You’ll need to add the correct grade of compressor oil before first use — running it without oil will cause immediate damage.

4. Is the A39B compatible with any ABAC compressor? It’s designed for ABAC’s A39B-based compressor range, typically fitted to 3–5 HP machines with 50-litre tanks and above. Always match it against your compressor’s model/serial number before purchasing, as belt sizing and mounting can vary between models.

5. What’s included when I order this pump head? The unit ships complete with a flywheel and air filter, so you have the core components needed to reassemble it onto your compressor’s motor and tank.

6. Should I install it myself or use a technician? While the swap is designed to be straightforward, we recommend a qualified compressor technician handle installation, since correct belt alignment, electrical connections, and oil filling are important for safety and performance.
