4011040785 AVENTICS Pressure Regulator 0821302558 - Woodworking Machine Spare

This is an AVENTICS pressure regulator, part number 0821302558, that fits Homag woodworking machines as a spare for Homag part number 4-011-04-0785. It has a G 1/4 port, a nominal flow of 2000 L/min, mechanical activation, and seals made of acrylonitrile butadiene rubber. It weighs 0.4 kg. To confirm fitment, check the part number on the machine against 4-011-04-0785 and the regulator's port size against G 1/4.

When a pressure regulator fails on a Homag machine, the usual signs are erratic air pressure at the tool or clamp, or a regulator that no longer responds to adjustment. This spare, part number 0821302558, is the replacement for Homag part number 4-011-04-0785, so you can restore the machine's pneumatic control without adapting the pipework.

The unit is a standard pressure regulator with a G 1/4 port and a nominal flow Qn of 2000 L/min. Its seals are acrylonitrile butadiene rubber, and it weighs 0.4 kg. It fits Homag woodworking machines that call for part number 4-011-04-0785. Confirm the fit by matching that number on the machine's parts list or the old regulator, then check the port thread is G 1/4.

Before mounting, check the port thread and the seal condition. The regulator has mechanical activation, so adjustment is made directly at the unit. A G 1/4 port means it connects to the existing line without adapters, and the 2000 L/min flow matches the machine's demand.

Supply is as a spare part only. No customisation or special packaging is stated, so order by part number 0821302558 or Homag 4-011-04-0785. When you enquire, send the machine model, the part number from the old unit, and the quantity you need. That lets the supplier check the stock against the exact regulator without back-and-forth.

What the specification fixes, and what it leaves to the machine:

• Direct replacement for Homag machines — Homag part number 4-011-04-0785 matches this regulator, so you can replace the old unit without changing the machine's pneumatic layout or pipework.
• Port size for line fit — A G 1/4 port connects to standard pneumatic fittings, so the regulator threads onto the existing line without adapters or extra parts.
• Flow capacity for machine demand — Nominal flow Qn of 2000 L/min means the regulator can pass the air volume the machine's circuit requires during normal operation.
• Seal material for air service — Acrylonitrile butadiene rubber seals are used in the regulator, giving a known material to check against the air supply and operating conditions.
• Mechanical activation for direct adjustment — Mechanical activation means you set pressure at the unit itself, so no separate control signal or wiring is needed during setup or tuning.
• Weight for handling and mounting — At 0.4 kg, the regulator is light enough to handle during installation and does not add significant load to the mounting point.
• Standard regulator function — Standard pressure regulator function means it performs the usual pressure-reducing role in the pneumatic circuit, matching the original equipment behaviour.

What changes on the shop floor when the right part goes back in:

• Restores pneumatic control. Fitting the correct regulator brings pressure regulation back to the machine, so clamps and tools receive steady air and the machine runs as intended.
• Avoids adapter work. The G 1/4 port matches the existing line, so you do not need to source adapters or rework pipework when replacing the old regulator.
• Matches machine air demand. With a nominal flow of 2000 L/min, the regulator is sized for the circuit, so it does not become a bottleneck during normal machine operation.
• Simple mechanical setting. Mechanical activation lets the fitter set pressure directly at the unit, with no extra control wiring or signal source to connect during installation.
• Known seal material. Acrylonitrile butadiene rubber seals give the buyer a defined material to compare with the air supply, so there is no guesswork about compatibility.
• Light for easy handling. At 0.4 kg, the regulator is easy to carry and position during maintenance, which helps when access around the machine is tight.
• Two references for ordering. Both 0821302558 and Homag 4-011-04-0785 are available to quote, so the buyer can cross-check the order against the old unit before dispatch.

Check the Homag part number on your machine or old regulator against 4-011-04-0785. If it matches, this regulator is the spare for that position.

The port is G 1/4. That is the thread size for the pneumatic connection, so check your fittings match before ordering.

Nominal flow Qn is 2000 L/min. This is the air volume the regulator is rated to pass under the stated conditions.

The seals are acrylonitrile butadiene rubber. That is the material to check against your air supply and operating conditions.

The regulator weighs 0.4 kg. That is the unit weight for handling and shipping reference.

Activation is mechanical, so pressure is set directly at the unit. No separate control signal or wiring is required.

No customisation is stated for this spare. Order by part number 0821302558 or Homag 4-011-04-0785 to get the standard regulator.

Send the machine model, the part number from the old unit, and the quantity. That lets the supplier confirm the exact regulator against your machine.
