HII 2G series electric gas booster — **HII 2G series**Two-stage or double-acting electric gas booster, with integrated cooling fan.

Depending on the selected size, the electric gas booster can generate up to 14.500 psi (1000 bar) and is compatible with almost all gases, including air, nitrogen, helium, argon, hydrogen, oxygen, natural gas.

Thanks to the equipped gear motor, it maintains a constant flow rate as the pressure increases. The booster is equipped with 2 adjustable micro switches to stop the engine when the desired pressure is reached, or in the event of a lack of gas to be compressed, the gas inlet filter, gas line isolation valve and exhaust valve

The electric gas booster series 2G is designed for filling or topping up high and low-pressure cylinders. Available in a two-stage or double-action version, it stands out for the absence of belts or pulleys, making it the quietest in its category with a noise level of only 63 dBA. An additional advantage is the forced air cooling system, which reduces compression heat and prolongs the life of the seals.

Its innovative design and advanced features make it a unique product in the market, ensuring efficiency, quiet operation and longevity.

Electric or air driven gas booster?

Both technologies compress gas up to very high pressures, but they suit different plants. The electric gas booster is the right choice when compressed air is not available or is expensive, or when you need a constant flow as pressure rises.

	Electric gas booster	Air driven gas booster
Power source	2 HP electric motor, single or three phase	Compressed air (drive air)
Energy consumption	Lower	Higher, depends on the compressed air consumed
Flow as pressure rises	Constant, thanks to the gear motor	Decreases as the pressure ratio increases
Best for	Cylinder filling and topping up, test benches without a compressed air network, hydrogen with dedicated versions	Plants with an existing compressed air network, intrinsically safe installations

Advantages of the HII electric gas booster

No pneumatic power supply needed
Motor power limited to 2 HP, single or three phase
Automatic start in the event of a leak downstream
Adjustable stall pressure and easy integration of automatic controls
Wide range of special modifications available

Our technicians, trained on gas pressure multiplier technology, can review your P&ID diagrams to ensure the whole system performs as expected, and support you after delivery.

Frequently asked questions

How do I choose the 2G series model?

Inlet pressure, outlet pressure and flow rate matter. The two-stage models reach the highest pressures (up to 14,500 psi with the 2G-1492), the double-acting ones have the highest flow (up to 22.2 SCFM with the 2G-3030, at 70 cycles/min).

What electrical supply does it need?

A 2 HP motor. The voltages in the catalogue are 115 V and 220 V single-phase, 208/230 V, 460 V and 380 V three-phase, at 50 or 60 Hz depending on the version.

Which options are available?

Among others: pressure switches with automatic stop and restart, dual outlet pressure control, 4-port manifold, remote start, variable frequency drive, pressure reducer, oxygen cleaning MIL-STD-1330D and watertight enclosure.

Can it be used with oxygen or hydrogen?

The catalogue offers the oxygen cleaning option (MIL-STD-1330D) and the option with vents connected to a common port for O2 and H2 service. Tell us the gas and the pressures: a technician will reply.
