Differential pressure gauge, square, for FUTURA and multifix series - Riegler 156358

Differential pressure gauge, for FUTURA and multifix series, BG 1 to 4, G 1/4, G 3/8, G 1/2, G 3/4, G 1, angular design The DM 34-1 differential pressure gauge indicates the pressure drop between the inlet and outlet of the filter on which it is mounted. As part of filter monitoring, for example, it can be used to detect when the filter element is clogged and needs to be replaced. Replacement of the filter element is recommended from a pressure drop of 0.35 bar (start of the red area on the display).

About Accessories and spare parts

This group collects spare and add-on parts around compressed air preparation, from filter elements and drain valves through solenoid coils to pressure gauges. It keeps existing filters, regulators and service units running without replacing the whole assembly. In total 755 items are available.

What matters when choosing

• Port thread: G 1/2 to G 2 are listed, along with female and male threads in G 1/4, G 3/8 and G 1/2. The spare part has to match the size of the installed device.
• Material: nickel-plated brass, steel, zinc-plated steel, zinc-plated sheet steel, steel with zinc flake coating, stainless steel, aluminium die-cast, anodised aluminium, zinc die-cast and the plastics PA 12, PA 66 and POM.
• Operating temperature: depending on the item, lower limits run from -10 to 0 °C and upper limits from 90 to 100 °C.
• Protection class on electrical parts: IP 65 to EN 60529 is stated, reached with the plug correctly fitted including its seal.
• Pressure rating of add-on parts: the drain valve version is rated 4 to 12 bar operating pressure and a maximum inlet pressure of 16 bar.

Typical applications

• Replacing spent filter elements at the planned service interval
• Retrofitting automatic drain valves on filters that are hard to reach
• Replacing failed solenoid coils without changing the complete valve
• Adding pressure gauges to regulators that ship without them
• Topping up special oil for mist lubricators and air tools

The 755 items come from twelve countries of origin, among them DE, IT, AT, GB, PL and HU. Electrical components carry IP 65 to EN 60529 with the plug and seal correctly fitted.
