Answer:
The V-7700 ABEK2 uses a standard 40 mm RD40 thread connection conforming to IS 14138 (Part 1):1994. It mounts directly onto Venus full-face masks (such as V-667, V-999, and V-997) as well as standard 40 mm PAPR breathing tubes.
The Venus V-7700 series canisters are built with a standardized 40 mm threaded connection per IS 14138 (Part 1):1994 (RD40 thread). This provides cross-compatibility across compliant respiratory gear:
- Venus Full-Face Masks: Direct screw-in fit to the front port of the Venus V-667, Venus V-999, and Venus V-997 full-face respirators.
- Powered Air-Purifying Respirator (PAPR) Systems: Interfaces directly with Venus PAPR breathing hose connections utilizing standard 40 mm thread fittings.
Users must verify that the sealing gasket inside the mask port is intact and conduct positive and negative pressure seal checks prior to entering hazardous atmospheres.
