Product detailed description
The AirCom RPM10-120 low-pressure regulator reduces the pressure of compressed air from the air network – 1 to 15 bar – to 10 to 120 mbar, i.e. 0.01 to 0.12 bar. The large diaphragm detects even a small change in pressure and keeps the outlet constant. A ⌀ 63 mm pressure gauge with a 0–250 mbar scale is included.
Size RPM 10, connection G 1", flow rate 1,400 l/min, adjustment: adjusting screw with lock nut. It belongs to the series of RPM low-pressure regulators.

The diaphragm cover has a diameter of 245 mm. The pressure gauge is screwed in from the side into the G 1/4" connection.
Installation and adjustment
- install a compressed air filter upstream of the regulator – the manufacturer recommends it; the internal strainer only provides protection during installation
- blow out the pipework before installation; dirt would damage the valve seat
- connect the regulator according to the arrow on the body (IN → OUT); any mounting position is possible; do not use lubricant during installation
- screw the pressure gauge into one of the side connections G 1/4" and close the other one with the supplied plug
- before pressurising for the first time, release the setting so that the spring is not tensioned; then always set the pressure by increasing it, i.e. from below
- secure the setting with the lock nut
Accessories and spare parts
- RPM 10 is mounted directly in the pipework; the manufacturer does not supply a bracket for it
- we will find a spare diaphragm or repair kit for you on request
- parts for other regulators: spare parts and accessories for pressure regulators
For higher pressure and high precision, there are FDR regulators (from 0.05 bar), and for 0–11 bar set on a scale MANO R dial regulators.

AirCom Pneumatic GmbH from Ratingen, Germany, is a specialist in pressure and flow control of gases and liquids. Its range includes pressure regulators from miniature to high-pressure, precision and proportional regulators, compressed air treatment, pressure switches and pressure transmitters.
From AirCom we offer RPM low-pressure regulators, which hold a constant pressure from 5 to 1500 mbar, and DRPA proportional pressure regulators, which set a pressure of 0 to 16 bar according to an electric signal of 0–10 V or 4–20 mA. Plus a mounting bracket for the RPM 12 and software for setting up the DRPA.

How to choose and connect an AirCom regulator
1. Manual or electric setting
An RPM regulator holds a constant low pressure that you set once by hand. If the machine control system is to change the pressure, choose a DRPA proportional regulator.
2. Range and size
Choose the smallest range that your pressure fits into – the setting will be finer. Choose the size by the flow in the table above. Mind the units: 1 bar = 1,000 mbar.
3. Prepare the air
Install a compressed air filter upstream of the regulator. The DRPA works with lubricated and non-lubricated air filtered to 50 µm; keep the inlet pressure at least 10 % above the highest pressure to be set.
4. Connect and set
Connect the regulator according to the arrow on the body. On the RPM always set the pressure upwards and lock it with the lock nut. Connect the DRPA via the M12 connector to the 24 V DC supply and the control signal.
Frequently asked questions
- What is the difference between RPM and DRPA?
- The RPM holds a constant low pressure from 5 to 1500 mbar that you set by hand. The DRPA sets a pressure of 0 to 16 bar according to an electric signal from the control system and constantly monitors the outlet pressure with a sensor.
- Does the RPM regulator come with a pressure gauge?
- Yes, a ⌀ 63 mm pressure gauge with a scale matching the range is included. It screws into one of the two G 1/4" side ports.
- Do I need software for the DRPA?
- No, the regulator is factory-set. The software with RS-232 converter is useful if you want to change the zero point, range, ramp or control parameters, monitor the pressure curve or troubleshoot.
- What does the DRPA do if the signal or supply fails?
- It exhausts the outlet. It fills and exhausts the outlet with the same flow and consumes no air itself.
- What does the manufacturer call these regulators?
- The RPM 12 corresponds to type AirCom R161-04, the RPM 10 to type R160-08 and the DRPA to the PP series (proportional regulators with digital control). The full RPM type designation is on each regulator’s product page.
- Where can I find all regulators?
- RPM regulators are in the category RPM low-pressure regulators, DRPA in the category proportional pressure regulators – together with other proportional regulators.
