Versions
Choose the version at the top of the page. All versions have the same thread, range and flow; they differ in the filter and lubricator bowls.
What it is for
It goes before a branch of the air line or a machine with high air consumption that needs clean air at a constant pressure with oil mist. The lubricator only adds oil from a flow of 167 l/min, so a smaller unit is more suitable for individual smaller tools.
Parts for this size: mounting kit 281-26 · filter bowls 322-122, 322-123, 322-124, 322-125, 322-126, 322-127 · lubricator bowls 327-111, 327-112 · filter elements 281-14 · regulator diaphragm 280-219 · sealing cone 280-218 · bowl sealing ring 279-9.
Maintenance
Drain the condensate regularly through the manual drain at the bottom of the filter bowl. Top up the oil in the lubricator bowl in good time; the lubricator can be filled even under pressure. Replace a clogged filter element; spare elements are in our range. Do not clean the plastic bowls with solvents.
Ventilek’s tip
Oil only at high consumption. The lubricator starts dripping from a flow of about 167 l/min. When the unit supplies only small tools, it does not add oil to the air.

EWO is a Stuttgart brand of compressed air fittings and oxy-fuel equipment. The company was founded by Emil Wolf in 1914, has been run by the Holzapfel family since 1938 and has carried the name ewo since 1939. It develops and manufactures in four areas: air preparation, compressed air accessories, air service equipment for workshops and filling stations, and oxy-fuel and propane welding equipment. Our range includes blow guns and nozzles, pressure regulators, air treatment units, tyre inflators and spray guns.
You will find EWO products in industry, car workshops and at filling stations. The BG269 and BG470 blow guns share the same M12 × 1.25 nozzle thread, so you can change the nozzle to suit the job. The pressure regulators cover ordinary air lines as well as high-pressure applications with inlets up to 200 bar.

Choose a regulator or air treatment unit by the flow your equipment needs and the outlet pressure you have to set.
How to choose and connect a blow gun
1. Choose the connection
Pick the gun with the connection that matches your hose: a DN 7.2 plug for a quick coupling, a 6, 9 or 13 mm hose tail, or a 1/4″ female thread.
2. Choose the nozzle
The basic nozzle gives a concentrated jet. Where noise is a problem or dirt may fly back, use a low-noise or safety nozzle, and a long nozzle to reach deep into a machine.
3. Set the pressure
The guns work at 2 to 6 bar and withstand a maximum of 10 bar. Reduce higher line pressure with a regulator upstream of the gun.
4. Hang it up and look after it
Both BG269 and BG470 guns have an eye for hanging on a balancer. Only change the nozzle with the gun disconnected from the air supply, and keep the thread clean.
Frequently asked questions
- Which nozzles fit EWO blow guns?
- The BG269 and BG470 guns have an M12 × 1.25 nozzle thread. They take the nozzles from our M12 × 1.25 nozzle category: basic, low-noise, safety, injector, long and flat.
- What is the difference between BG269A, BG269L and BG269E?
- All three are all-metal guns with a lever trigger and the same nozzles. BG269A has a forged aluminium body, BG269L a cast aluminium body, and BG269E is a forged gun with an adjustable maximum flow, for example for cooling and blowing out moulds.
- What does secondary venting on a regulator mean?
- When you lower the outlet pressure, the regulator vents the surplus air downstream by itself, so the pressure drops straight away. All EWO regulators of the 274, 280, 286, 302, 406, 417 and 120 series have it.
- When should I choose COMBIBLOC and when STANDARD?
- COMBIBLOC combines filter, regulator and lubricator in one body and takes up little space, with flow up to 3,400 l/min. STANDARD is for branch lines and high-consumption machines, with G 3/4″ to 2″ threads and flow up to 12,678 l/min.
- Is the Euroair inflator suitable for a tyre shop?
- Yes, the Euroair TGE range is designed mainly for filling stations and trade workshops. It has an 80 mm gauge in a protective cover and is also available with a calibrated gauge. The 0–25 bar range is for aircraft and special tyres.
- Where are EWO products made?
- The brand is owned by Hermann Holzapfel GmbH & Co KG, which develops and manufactures in Stuttgart, in the Stuttgart-Vaihingen industrial area since 1955. Every part goes through several inspections during production. The company has a quality management system certified to ISO 9001 and, for pressure measuring instruments, a certified production quality system (Module D) under the German Measures and Verification Ordinance.
