Robust, Durable, and Quiet
In addition to the excellent chemical resistance and exceptional gas tightness (5 × 10-5 mbar × l/s as a standard), these ex-proof models also feature the same affixed base rails with shock mounts as their N 630 siblings — well minimize noise and vibration.
Certified with Directive 2006/42/EC
A terminal box in the flameproof motor is available for easier installation and safer operation. All N 630 Ex models fulfill the criteria for completed machinery according to directive 2006/42/EC, therefore come with the CE mark.
