bioBUBBLE anterooms or airlock rooms are softwall enclosures available with dedicated positive or dedicated negative airflows. They can also be designed to convert between positive and negative pressures to adapt to changing environmental needs.

Constructed in any size or configuration to suit the needs of your specific application, durable, economical anterooms or airlocks are available as an option on any bioBUBBLE cleanroom or containment enclosure. 


bioBUBBLE anterooms and airlocks are constructed using:

  • A modular anodized aluminum framework
  • A clear vinyl skin with hook and loop fastener connections (tinted and opaque vinyl optional)
  • Blowers with long lasting, energy efficient, electrically commutated motors
  • 99.99% efficient HEPA filters


Dedicated Doffing Space: Negative pressure bioBUBBLE anterooms provide containment barrier areas for personnel to perform doffing procedures prior to exiting BSL-2, BSL-3, and BSL-4 areas.

Dedicated Donning Space: Positive pressure bioBUBBLE anterooms provide a HEPA-filtered, exclusion environment that controls entry into cleanrooms. Positive pressure anterooms also maintain the integrity of sterile gowning materials and personal protective equipment (PPE).

Docking Systems: Provide a suitable location for the introduction of sterile materials under aseptic conditions. bioBUBBLE designs and manufactures custom docking systems to mate with autoclave containers, glove box isolator ports, pass-through boxes, or any other equipment. Talk to us about your procedures.

Air Barriers: Create air barriers for effective isolation of specific rooms and areas within your facility.

Solve Air Balance Problems: Compensate for improper air balancing that may be present with older or problematic building ventilation systems.

Eliminate Disease Transmission: Reduce the possibility of airborne transmission and transference of pathogen-laden airborne particulates.

Regulatory Compliance: Assist with personnel compliance of regulatory guidelines without the need for permanent, invasive, and expensive hard construction.

Features and Benefits

Environmental Separation: The bioBUBBLE anteroom offers a portable, low cost, non-invasive method of achieving environmental separation within your facility, regardless of the air balance of the hard room.

Isolation: Effectively isolate individual hard rooms, allowing your facility to utilize mixed-use corridors while eliminating concerns of cross-contamination between individual rooms.

Assist with Standard Operating Procedures: Provide dedicated areas for implementation of standard operating procedures (e.g., donning and doffing) to help with protocol reinforcement.

Installation and Training: bioBUBBLE offers complete on-site installation and training performed by qualified bioBUBBLE technicians with little to no interruption of the workflow in your facility.

Energy Efficient: Power units in bioBUBBLE anterooms use electronically commutated motors for energy savings.
