Frequently Asked Questions (FAQs)
1. What is the ABAC A29B pump head used for?
It’s a genuine replacement pumping unit for ABAC belt-driven piston air compressors, used when the original pump wears out or needs servicing to restore full compressor performance.
2. Is the A29B pump head compatible with all ABAC compressors?
It’s designed for ABAC’s A29B-based belt-drive compressor range, generally covering models with tank sizes from 27 to 200 litres. Always check your compressor’s model/serial number against the ABAC parts catalogue to confirm an exact match before purchasing.
3. Does the pump head come with oil already filled?
No. The A29B pump head is supplied dry. You must add the correct grade of compressor oil before running the unit — running it without oil can cause immediate and permanent damage.
4. What’s included in the box?
The pump head is supplied complete with a flywheel and air filter, so you have the core components needed to complete the assembly onto your compressor’s motor and tank.
5. Can I install this pump head myself, or do I need a technician?
Basic mechanical knowledge is enough for most experienced users, but because it involves belt alignment, electrical motor connections, and pressure-rated components, we recommend installation by a qualified compressor technician to ensure safety and warranty compliance.
6. Does ADEX offer warranty and after-sales support for this pump head?
Yes, genuine ABAC parts purchased through ADEX are backed by manufacturer warranty terms and ADEX’s after-sales and spare parts support across the UAE.
