Filter regulators

ASCO Numatics introduces a range of Series 342 Stainless Steel Filter Regulators to complement the existing range of air service equipment. Suitable for inlet pressures up to 10 bar, the 1/4” and 1/2” NPT filter regulators have a fully stainless steel construction and comply with the requirements of ASTM A351/NACE MR 01.75.

The moulded reinforced diaphragms offer a large flow and the fine pitch/dual springs ensure accurate and steady regulation, regardless of input or output pressures. With a 316L stainless steel filtering element (25 & 5μm), the regulators are suitable for compressed air and gases. A finned diverter guarantees effective moisture removal. The regulator bowl has a manual bleed to drain condensate. An automatic drain is available as an option.

The smooth design facilitates easy mounting and there is a separate connection for the optional pressure gauge. In addition to an impressive flow rate ranging from 2380 to 4430l/min, the filter regulator is suitable for ambient temperatures from -40 up to 80°C (-50°C for arctic conditions is available on request).

The series 342 stainless steel filter regulator can be installed across many industries, including chemical, petrochemical, offshore and oil & gas, refinery, power generation, pulp & paper and process plants. Available as 1/4” and 1/2” NPT, the fully stainless steel design meets the requirements of NACE MR 01.75 and is certified to ATEX II 2 G/D c IIC X and SIL.
