What are the Axiom’s advantages over Type B1 and B2 BSCs?
The Axiom outperforms each of the Type B BSCs in regards to safety and flexibility. Though similar in airflow to a B1, the Type C1 does not require special considerations when handling hazardous chemistry, nor does it require a dedicated exhaust system. A B1 BSC cannot operate without exhaust and therefore will always require the infrastructure and cost associated with moving expensive tempered air. The Axiom can be removed from ductwork, eliminating or reducing the cost associated with exhaust air.
A Type B2 BSC experiencing a remote exhaust failure can pressurize the work zone, pushing contaminated air into the laboratory. The C1 BSC is easily adapted and/or manifolded into an existing building exhaust system, and should there be a failure, it protects the laboratory and the operator for an additional 5 minutes. Type B2 BSCs also heavily tax exhaust systems with large volumes that can exceed 1,200 CFM – this can cost over $100,000 per BSC to operate over its life. The C1 reduces this volume by over half, saving over $50,000 per BSC.
An A2 can be ducted to handle odors and non-hazardous chemistry and it is easily adapted to exhaust systems. It can never offer the chemical protection of the Type B or C BSCs because it does not have single-pass airflow.
Type A and Type B BSCs cannot be retrofitted, altered or otherwise made into the other type of cabinet. The Type C1 adopts the strengths of the Type A and B BSCs while addressing their limitations and is cross functional.
