Frequently Asked Questions
What tyre valve types does the MK4 support?
The MK4 is supplied with both an 8V1 twin hold-on connector and a 12V1 in-line screw-on connector, covering the two most common aviation tyre valve standards without requiring additional adaptors.
What compressor supply pressure does the MK4 require?
The inflator accepts a maximum inlet pressure of 362 PSI (25 bar). For optimal flow performance of 500 l/min, a supply of 13 bar is recommended.
Is the MK4 suitable for outdoor and cold-weather use?
Yes. The MK4 is rated for operating temperatures from −15°C to +55°C, making it suitable for year-round use in hangars, aprons, and outdoor maintenance environments.
Why is the 4G1 armoured hose significant?
4G1 hydraulic oil-resistant armoured hose is rated for high-pressure pneumatic applications and resists degradation from oils, fuels, and hydraulic fluids commonly found in aviation workshop environments — ensuring long service life under daily professional use.
