Flex Twin Air Compressor Kit, 12V with Wiring Harness

Short Product Summary

The Flex Twin Air Compressor is a 12V compressor kit built around high airflow: 174.3 L/min with no load and 131.7 L/min under load. It arrives fully assembled and tested, with a wiring loom, a dash isolating switch, two air filters and mounting hardware for installation. It is aimed at 4x4 owners who run large tyres and want proper on-board air.

Why This Product

Large tyres take a lot of air, so flow rate matters when you are bringing four of them back up after a sand run or a rocky pass. This kit is rated at up to 174 L/min, and its sealed, bearing-mounted motors and thermal overload protection are there to look after the compressor itself. With the harness, switch and filters in the kit, most of the install work is planning where each piece goes, and we recommend professional fitting.

Key Features

• High airflow – up to 174 L/min with no load, which suits large tyre sizes
• Sealed, bearing-mounted motors – a brush tensioning system aims at long life and low running noise
• Thermal overload protection – guards the motor against overheating
• Complete wiring harness – simplifies wiring in and connecting solenoid valves, with two fuses for backup protection if a fault occurs
• IP54-rated dash switch – lets you isolate the compressor from the dash
• Washable air filters – two relocatable, splash-resistant filters with sintered bronze cartridges
• Assembled and tested – the kit is supplied ready to install, hardware included

Ideal For

• 4x4 owners with large tyres who want quick re-inflation after airing down
• Overlanders and remote travellers who rely on their own air for tyre inflation
• Vehicle builders and fitters adding on-board air with a wiring loom and mounting hardware in one kit

Optional Fitment / Upgrade Notes

This is a higher-current kit, so plan the install before you order.

• Have the supply, cable size and fusing planned by a qualified auto-electrician. The kit is rated at a maximum of 65 A, so cable and fuse choices matter.
• Check where it will live: the unit measures H 102 × L 190 × W 275 mm and weighs 8.8 kg, and the two air filters can be relocated.
• Decide where the isolating dash switch will sit so it is easy to reach from the driver's seat.
• If you plan to run solenoid valves from the loom, ask us to confirm your set-up before ordering. We recommend professional fitting.

FAQ

How much air does the Flex Twin compressor deliver?
It is rated at 174.3 L/min with no load and 131.7 L/min under load.

Which flow figure should I plan around?
Flow falls once the compressor works against pressure, so the under-load figure of 131.7 L/min is the more realistic one for tyre inflation.

What voltage does it run on, and how should it be wired?
It runs on 12V. The kit has a wiring loom with two fuses, and we recommend a qualified auto-electrician sizes the cable and fusing for the 65 A maximum current.

What is in the kit?
The assembled compressor, wiring loom, dash isolating switch, two air filters, mounting bolts and washers, a rubber heat-protection fitting, an extra air chuck, a tyre pump nozzle and an NPT threaded pipe fitting.

Is the motor protected against overheating?
Yes, the motor has thermal overload protection.
