Portal de soplado de puerta fijo
A fixed doorless blow-off portal that directs filtered air across personnel at a compact doorway without creating a full enclosed air-shower chamber.
- Doorless Fixed Portal
- Side-Mounted Blow-Off Nozzles
- Compact Doorway Treatment
- Open High-Speed Passage
Introducción del producto
The fixed doorway blow-off portal is a permanent doorless open frame around a personnel opening, not a closed booth or a tall enclosed filtration tower. Compact side casings contain the air equipment and nozzle manifolds, while an overhead bridge ties the two posts together. Presence sensing can activate the blow-off airflow as personnel cross the open portal, providing a practical dust-removal point where a full airlock is not required.
Características clave
Side-mounted blow-off nozzles direct air across the passing person.
An overhead bridge aligns the two portal posts and protects routed wiring.
Lower inlet sections collect part of the disturbed dust close to footwear level.
Presence sensing can reduce operation when the passage is unoccupied.
Preocupaciones del producto del cliente
A fixed open portal must fit a shallow doorway while delivering useful airflow and retaining a stable structural connection to the surrounding partition.
The site does not have depth for a two-door chamber.Blow-off components are packaged in slim side casings around the existing opening.
Fast-moving personnel receive very brief airflow exposure.A closely spaced nozzle array can cover the crossing zone while presence sensing activates the system.
Two independent posts can lose alignment over time.A rigid overhead bridge and fixed anchors tie both posts into one portal frame.
A full enclosed unit would obstruct a busy passage.The doorless format preserves an open high-speed walking route.
