Optimized Alarm System

The new G400 MP-2 pump continuously communicates with the G450/G460 gas detector. This interaction allows fault indication via the detector display. Alarms such as low battery, blocked sampling line or interrupted power fault are shown on the display and activate a visual and audible alarm on the monitor.

Various Applications

Gas samples can be taken from a distance of up 100 meters (over 300 feet) at a typical draw rate of 0.5 liters per minute.

Superior Flexibility

The G400 MP-2 is the only detachable pump on the market today which will allow for operation in both diffusion mode and remote sample-draw mode. Simply slide the shutter to turn the pump on or off. When the pump is on, the shutter covers the diffusion inlets and exposes them when the pump is switched off.

The G400 MP-2 features a high efficiency redundant filter system in addition to a standard external probe with dust and hydrophobic filters.

Independent Power Supply

The G400 MP-2 is operated by its own power supply, independent of the gas detector. The power supply of the pump allows for up to 10 hours of continuous operation.
