Pre-fabricated (Modular) Bio-safety Laboratory

Biosafe provides Prefabricated/ Modular BSL-2/ BSL-3 facilities on turnkey basis. These labs are build into standard ISO shipping containers, in comply with WHO/ BMBL standards

Prefabricated Biosafety labs having modular structure, air flow control system , HVAC, PLC control system and other machineries are ready to use laboratories with minimum onsite installation work.

Laboratories are tested prior to shipment, furnished with Biosafety cabinets, Double door autoclaves , Pass Box and other necessary equipments suitable for handling Air borne infectious microorganism such as TB, swine/ Bird flu virus, streptococcus pneumoniae etc.

These Prefabricated Labs are used globally to support the wide range of operations traditionally carried out in conventional buildings.

HVAC System


HEPA Filter

  • All air supply and exhaust are HEPA filtered
  • HEPA filter of 99.99% filter efficiency of 0.3um particle size



  • Built at the room exhaust point and main exhaust point
  • 99.99% filter efficiency of 0.3um particle size
  • Completely airtight
  • Easy for maintenance

Supply and Exhaust System

  • Independent supply and exhaust system
  • Unidirectional inward air flow
  • None-recirculation, 100% total exhaust
  • Sealed and air tight, stainless stell made all welded ducting
  • Digital pressure gauges to measure and monitor pressure
  • Equipped with high-performance valve to control the negative pressure stable
  • Equipped with audible alarm to detect any pressure and temperature failure
  • Equipped with air tight damper to permit airtight for decontamination



Easy Maintenance

Digital pressure gauges to measure and monitor HEPA resistance. If the resistance reaches the limitation for filter well-work, visual alarm in User Interface will remind to replace a new filter.

Spare spaces have been left in design for the purpose of changing HEPA filter, cleaning air duct and maintenance of equipments.

Waste water treatment

Waste water treatment system is equipped with chemical waste water treatment system for wate water generated from the laboratory. The whole treatment procedure can be accomplished automatically using chemical disinfectant.

Uninterrupted Power Supply/UPS

Uninterrupted power supply system is designed to provide continuous power to damper, controls and biological safety cabinet in the event of power failure from the source/city. Holding time can be selected to provide sufficient time to execute emergency protocol or activate backup electrical generator.

Standby exhaust blower

Standby exhaust blower is designed to switch on almost instantaneously when the original exhaust fails, ensuring the room maintains negative pressure.


The system is designed for easy decontamination. Regular decontamination service is provided during the defect liability period/warranty period.
