The 4210 series regulator, also known as the “Trigger” is designed to provide aerosol capability. The "Trigger" can be used with the 2AL, 8AL, and 6D cylinders. Pressing the trigger activates the regulator and dispenses gas at a preset flow rate of 4 LPM. The trigger can also be locked in the “on” position for continuous gas flow. Preset flow rate of 4 LPM with cylinder pressure gauge.

This regulator is an excellent alternative for bump testing gas monitors. Instead of using the aerosol can that lasts only 3 months and cannot be used to calibration your monitor. Simply put 4210 regulator on your calibration gas cylinder (34L or 58L) and use it for bump testing.
