Harris KH1100 Regulator for Industrial Air

The Harris KH1100 is a two-stage cylinder regulator built for industrial air service with a CGA-590 inlet connection. It delivers outlet pressure from 0 to 15 psi through a 1/4 in tube fitting. The body is chrome-plated brass with a 2.0 in diameter and uses a 316L stainless steel diaphragm. It includes a diaphragm-type shut-off valve and relief valve and meets CGA E-4 standards.

Thermals Noise and Power Draw

As a purely mechanical pressure regulator, the unit generates no heat, produces no audible noise and draws no electrical power during normal operation. The chrome-plated brass body and 316L stainless steel diaphragm maintain stable delivery pressure without active cooling or energy input. Two integrated gauges display supply pressure up to 4,000 psi and delivery pressure without external instruments.

Sustained Load Behaviour

Under continuous flow the two-stage design keeps outlet pressure steady as cylinder supply pressure declines from the 3,000 psi maximum inlet rating. The diaphragm shut-off valve and relief valve provide over-pressure protection throughout extended use. No performance degradation occurs over time because there are no electronic or moving parts subject to thermal stress.

Questions about this item

How do I install the Harris KH1100 regulator on a cylinder, and what step is often missed?

Connect the CGA-590 inlet to the cylinder valve, tighten with a wrench, then open the cylinder valve slowly before adjusting the delivery pressure to 0 to 15 psi; the step often missed is leak-testing the 1/4 in tube fitting outlet with soapy water before use.

What maintenance or replacement will the Harris KH1100 regulator need later?

The 316L stainless steel diaphragm and relief valve should be inspected periodically for wear or contamination; replace the diaphragm if pressure control drifts or the relief valve if it fails to vent at the set pressure.

What limit appears first on the Harris KH1100 during sustained use?

The delivery pressure range tops out at 15 psi, so extended high-flow demand will hit that ceiling before the 3,000 psi max inlet pressure or the 2.0 in body diameter becomes a factor.
