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 280-235 · 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.
