ATEX and Ex variants must be selected against the required zone, gas group, temperature class and the manufacturer’s declaration for that exact code. DOT versions are dedicated brake-fluid configurations. Confirm those requirements with Girovac before specification.
Select the motor and lubricant from the ordering-code table. Standard B, DOT brake-fluid and hazardous-location versions have different application limits. The standard performance figures shown here must not be applied automatically to DOT or other specialist builds.
For vapour-heavy processes, discuss gas ballast, condensate handling and exhaust filtration. Include the gas composition, duty cycle and working pressure when selecting oil, filters and accessories.
Manufacturer image illustrates this model range. Motor, lubricant and accessories vary by ordering code; confirm the supplied equipment on the quotation.
Explore the TRIVAC B and BCS range guide or the Leybold brand guide. Send the required working pressure, chamber volume or throughput, gas and vapour composition, electrical supply and connection sizes. For a replacement, include the existing nameplate and serial number.
