Product Introduction

An inflatable elastomer seal runs around the complete door perimeter and expands against the closed blade when supplied with compressed air. Stainless construction forms the leaf and architrave, while dedicated controls monitor both seal pressure and the incoming supply. The frame-to-floor detail is kept flush for passage. This arrangement differs from a fixed compression gasket by actively applying and releasing seal contact as part of the door operating sequence.

Pressure monitoring makes the seal supply condition observable.
Four-sided contact includes the bottom of the opening.

Solutions for Your Application

How can operators identify a loss of sealing air?

The control arrangement monitors incoming air and seal pressure rather than relying only on door position.

Could the lower sealing detail obstruct the passage?

A flush floor interface allows the inflatable gasket to form bottom contact after the blade is closed.

Available Options

Flush glazed observation panel.
Pneumatic seal-release override and backup supply options.
