Compressed Air Stirrers, Buddeberg

1 PLR compressed air laboratory stirrers up to 25 l for use in potentially explosive atmospheres

PLR compressed air laboratory stirrers are designed for all kinds of standard mixing tasks. The vane type, air-driven motor offers a high power density and is significantly lighter and smaller than an equivalent electric motor.

General specifications:

Operating pressure max. 6 bar
Air consumption 260 l/min at 6 bar
Power output 200 W at 6 bar
Clockwise rotation

ATEX certification in accordance with Directive 94/9 EG

Basic models include:

All-stainless steel housing, grade 1.4305
Continuously adjustable speed control valve
Support arm Ø 14 mm
Tubing nozzle connector Ø 9 mm
Output shaft (L x Ø) 26 x 10 mm
