Thiscan be calculated with the following formula: Mass m [kg ]:m = L x B x H x ρ L = lenght [m] B= width [m] H = hight [m] ρ= density[kg/m3] Example: m = 2,5 x 1,25 x 0,0025 x 7850 m = 61,33 kg xample of Vacuum calculation System design - the procedure

EJECTORS - Graham Corporation designs and builds vacuum .

Single-Point Design. If only one load and vacuum are required for a particular application, single and multistage ejectors can be designed specifically for one condition. This saves steam. Occasionally, however, single-point design ejectors are not always stable at very light loads or at loads slightly in excess of design.

Vacuum Ejectors - Schmalz

Vacuum generators provide the required vacuum. The vacuum is generated either pneumatically (ejectors) or electrically (pumps, blowers). Pneumatic vacuum generators implement short cycle times and can be integrated directly into the system due to their compact and lightweight design. Ejectors offer intelligent functions for energy and process .
