The 56 series pneumatic timer has a geared timing mechanism for precision, designed with conventional sweeping timing hands and a large rotary knob for quick and easy operation.

The 56 series pneumatic timer is a well-known and favourite standard industry device with impressive +/-1% repeat accuracy. A motor mechanism driven by air provides precise timing regardless of air pressure fluctuations.

The 56 series pneumatic timer replaces Kuhnke pneumatic timers 54.021, 54.022, 54.023, 54.024, 54.025 and 54.026.

There are six models to choose from seconds, minutes or hours with delay ON and delay OFF timing.

ON or OFF delay timing is achieved by blocking ports of a 5-way valve with a blanking plug. Set the time by adjusting a large rotary knob. A black timing hand shows the preset time, and a red timing hand the remaining time.

The pneumatic clock face timer consumes 9 litres of air per minute at the control port to power the air-driven mechanical motor. On reaching a preset time, the valve switches, and the timer continues to use air while the control port is powered.

Connections are to the rear of the pneumatic timer. Spring clips secure the timer to the panel, or use an aluminium bracket (ordered separately) to mount these timers to a surface.

When used within its design parameters, this product has no potential for ignition; therefore, use within an ATEX environment is possible. Product group IIG/IID, category 3, zones 2 & 22, not downhole or mining applications requiring full independent certification.
