Off-grid means the customer doesn't have a 380 V three-phase feed available — the compressor brings its own engine. EMAX covers this market with the diesel PSD-185 (49 HP, 5 m³/min @ 7 bar, 1085 kg) for 24/7 mining and oilfield service, the petrol PSP-35F for line construction and remote utilities, and the patent-protected TT-4IN1 mobile power station that doubles as a 6 kW generator + 130 bar pressure washer + battery charger + air compressor on one Honda GX390 platform. The TCGW-3IN1 (compressor + welder + generator on one engine) covers field fabrication. Petrol-Tube series TD-6505PH / TD-6516TPH for the smaller portable demand. Honda branding throughout where applicable; CE + portable certification on the pressure vessels.
The PSD Series is EMAX's diesel-driven portable screw line — built for off-grid sites where a 24/7 air supply has to ride through fuel fills and a generator isn't practical. PSD-185 ships with a 4-cylinder WP-series diesel direct-coupled to the screw airend, 5 m³/min at 7 bar, 1085 kg gross.
PSP runs a screw airend off a Honda petrol engine — designed for off-grid sites where 3-phase power doesn’t exist yet. Used by line construction, remote utilities, and monsoon-zone agriculture.
TT-4IN1 is EMAX's patent-protected mobile power station — one Honda GX390 13 HP engine driving four functions on one chassis: 6 kW generator (7.5 kW max), 130 bar / 9.5 L/min high-pressure washer, 12V/8.3A battery charger, and an 8 bar / 275 L/min air compressor with 18 L tank. Used by emergency response, mobile maintenance, agricultural, and remote infrastructure crews who can't afford to land at a site with three separate machines..
TCGW-50 packages a 540 L/min @ 12 bar piston compressor, a 20–170 A welder, and a 5 kW generator into one engine-driven chassis. One machine, one fuel feed, three on-site tools.
Petrol-Tube is the portable tube-format piston driven by a Honda GX200 — for job sites, remote utilities, and any operation that needs compressed air where 380V three-phase doesn't reach. Two tank sizes (TD-6505PH and TD-6516TPH); both ride on the same petrol engine + piston platform..
