airplay / aircop

Magnetic stirrer drives with pneumatic motor and conical connection. The "airplay" with NS 29/32 and "aircop" with NS 45/40

Modern and memorable
The proved technology of the pneumatic motor, combined with a magnetic stirrer is a new line. We present the combinations with a flanged connection, two conical versions or a threaded connection.

All-round function
The "air-" assembly consists of a permanent magnetic coupling and compressed air motor connected by a flange. Therefore, a cardan coupling is not required. The stirring system operates with little vibration and significantly reduces the height. Speed control is carried out variably using a fine adjustment valve and can be read out analog on a tachometer. The complete stirring system is supplied with an ATEX certificate. Different stirring tools can be installed on the drive shaft of ø 7 mm.

Example of application in Figure 2

The figure shows a magnetic agitating drive Type airplay, driven by compressed air, with joint, 90 Ncm, NS 29/32 on a 3 litre, double-jacket reaction vessel, with a cover NW 150. Depending on the reaction vessel, this series can be used for operation under vacuum and at temperatures up to 250°C. The complete agitating unit is designed for use in EX zones (ATEX).
