Product Overview

STERIS' VHP® M1000-T4 is a high capacity, safe & environmentally friendly method to allow for easy & efficient daily decontamination of large spaces.


STERIS’ VHP M1000-T Biodecontamination System utilizes Vaprox® Sterilant (EPA Reg. No. 58779-4) as a means of achieving dry, low temperature sterilization within large sealed enclosures such as cleanrooms and filling lines. The dry, gaseous process consists of four distinct phases:

Dehumidification - Humidity is removed from the room space via an integrated desiccant system. This is done to ensure that a true, dry biodecontamination process is achieved.

Conditioning - Vaprox is rapidly injected by the generator and converted into a dry vapor that quickly raises the level of hydrogen peroxide to an effective concentration.

Biodecontamination - Hydrogen peroxide vapor concentrations are maintained at the target concentration level to provide an effective kill of micro-organisms in the room space.

Aeration - The generator stops injecting Vaprox and accelerates the breakdown of vapor into its environmentally friendly base elements of water vapor and oxygen. Aeration continues until hydrogen peroxide is reduced to an acceptable level and the room is commissioned for regular use.


  • Productivity - Provides continuous high capacity decontamination of large spaces, >20,000ft3, such as clean rooms, production filling line isolators, pass-through chambers, etc.
  • Ease of Use - Can be integrated with building automation systems.
  • Flexibility - Can be conveniently integrated into pass-through chamber or aseptic filling systems or used to decontaminate entire suites or rooms in sequence.
  • Efficacy - The gaseous decontamination process is effective against a wide variety of microorganisms and has a broad range of material compatibility.
  • Green - Provides a non-toxic and environmentally friendly alternative to other decontamination processes. Vaporized Hydrogen Peroxide breaks down to water vapor and Oxygen. 
  • Secure - Write text saying Optional 21 CFR Part 11 data security package enables audit trail electronic data capture, user administration, and other features for use and validation.
  • Connectivity – Optional Anybus modules allow for easy integration into system network via EtherNet/IP, Modbus TCP, and PROFIBUS communication protocols.
