Product Description

Bubble Tight lsolation Damper

The isolation dampers are used to isolate the duct or bibo housings HEPA or carbon filters for purpose of decontamination for major
alternation works, replacement of filters,testing and air balancing.

Bubble Tight Dampers (BTD) or Air Tight dampers are of zero leakage are suitable for extremely high risk biosafety or animal biosafety
Laboratories levels L3 above, radioactive,nuclear and chemical safety.

Application

For exhaust air filtration of radioactive materials, pathogenic organisms, biological particles,dangerous and toxic substances.
Create a barrier between hazardous contaminants and filter change out components typical to a containment system.
Isolate contaminated filters and protect service personnel.

Construction
The damper is constructed of stainless steel 304, with flanges fully welded to both ends with minimum flange to flange distance of 200 mm.
Available in square flanges for easy BlBO housing connections. Bolting holes at flanges are provided.

Airtightness
The initial pressure was at least 3000Pa lower than the ambient pressure, the hourly leakage rate does notexceed 0.25% of housing volume.
The operation is manual, optional electric or pneumatic actuator.
