Pressurisation Systems
Product overview
RAFAVENT PRODUCT FAMILY
Air-movement equipment and project inputs for staircase, lobby and protected-space pressurisation strategies.
Pressurisation is a system duty, not a fan-only claim. The required airflow depends on leakage paths, door conditions, building geometry, control logic and the project fire strategy. RAFAVENT reviews fan requirements within the submitted design basis.
Calculated ranges for early model selection. Final duty, dimensions and materials are confirmed against the project requirement.
RAFAVENT Engineering Calculation — Preliminary Selection — Non-CertifiedThese values are engineering calculations, not AMCA/ISO certified ratings. Smoke, fire, temperature and hazardous-area certification applies only when supported by project-specific evidence.
Fan selection inputs for protected escape stair strategies.
Air supply duties for spaces defined by the project fire and smoke strategy.
Coordination with ducts, dampers, controls, standby power and pressure sensing.
Required airflow and static pressure
Operating temperature, humidity and air composition
Continuous, intermittent or emergency duty
Available power supply and control requirements
Space, mounting, connection and sound constraints
Approved pressure criteria, leakage calculation, door scenario and control sequence
