The Harris Model 301 regulators are compact single-stage metering regulators ideally suited for oxygen therapy applications using small cylinders or where space and weight limitations are important. The design of this regulator has made it a popular choice for home care, ambulance, hospital transport or doctors/dentists offices. This regulator features sintered bronze filters in the inlet port and outlet fitting; captive adjusting knob; internal relief system to guard against over-pressurization; a yoke with a unique neoprene/metal seal that establishes a positive cylinder union by simply hand tightening and pressure gauges that meet ANSI B-40.1 specifications.

The Model 355-2 is a compact, combination flowmeter and regulator designed to deliver an adjustable flow up to 15 LPM. The Model 355-2 is designed to maintain accurate delivery, even when upstream pressure fluctuates. The regulator also features a captive inlet nut to protect the seat; an internal relief system to guard against over-pressurization; flow tube easily read from different angles; and a color coded pressure gauge engineered to ANSI B-40.1 specifications. The Model 355-2 is commonly used in hospitals and home care applications for nebulizers, humidifiers, masks and tents.
