Engineered for Safety,
Designed for Life
The HAPU30 — a pressure-differential-insensitive fire & escape door. Integrated compensation valve equalizes up to 450 Pascal in ≤0.8 seconds. Built for smoke-pressurized stairwells.
High Pressure.
High Stakes.
When smoke pressure systems activate in stairwells, they generate up to 300 Pascal of positive pressure. Conventional fire doors become nearly impossible to open — blocking self-rescue and delaying emergency responders at the worst possible moment.

Equalization.
The integrated pressure differential compensation valve activates the moment you touch the handle. In 0.2 seconds, force drops to ≤75 N — meeting DIN EN 12101-6. By 0.8 seconds, ≤50 N — full barrier-free operation for all users, under any conditions, up to 450 Pascal.
View Product →FR 30 Certified
30 minutes of certified fire resistance under DIN 4102-5 and EN 1634-1. The door maintains structural integrity and prevents flame passage for full evacuation time in any emergency scenario.
RS Smoke Sealed
Certified smoke tightness class RS per DIN 18095-1 and EN 1634-3. Precision polyurethane seals block toxic smoke at ambient and elevated temperatures — across 200,000+ opening cycles.
Barrier-Free Always
After pressure equalization within 0.8 seconds, opening force is ≤50 Newton — meeting DIN 18040-1 / DIN 18040-2 for barrier-free operation. Safe for everyone, including those with reduced mobility.
