High Power Vacuum Pump
is supplied to produce cycle
vacuum pulses that remove air and moisture from chamber.
Direct drive rotary vane pump is quiet (<60 dB) with low
vibration. Powerful 3 HP (2.2 kW) motor produces a
displacement of 53 CFM (90 m
3
/hr) and helps alleviate moisture
sensitivity in biodecontamination unit. Biodecontamination unit
operating pressure is from atmospheric pressure down to less
than 1 Torr.

CYCLE DESCRIPTION
The VHP MD140X Biodecontamination Unit is equipped with
three programmed Biodecontamination Cycles: Lumen Cycle
(55 minutes), Non Lumen Cycle (28 minutes) and Flexible
Cycle (35 minutes). Each Biodecontamination Cycle proceeds
through three phases: CONDITION, BIODECONTAMINATION
and AERATION.
Basic description of a Biodecontamination Cycle (example):
•
CONDITION
— This cycle phase is a set time vacuum
pulse to remove air and moisture from the chamber. When
setpoint is reached, load is tested for acceptable moisture
content. If content is acceptable, cycle proceeds. If not,
Condition pulse repeated.
NOTE: If Condition phase fails the second moisture check,
the cycle Aborts.
•
BIODECONTAMINATION
— This cycle phase is a series of
four pulses. Each pulse consists of: vacuum pulled to
setpoint; Vaprox 59 Hydrogen Peroxide Sterilant vapor
drawn into chamber; hold for programmed time; filtered air
is introduced to setpoint; hold for programmed time; deep
vacuum pulled to setpoint.
•
AERATION
— This cycle phase pulls a vacuum to
setpoint and continues to evacuate for programmed time
to reduce chamber vapor concentration. Once Aeration
phase is complete, chamber pressure returns to
atmospheric and chamber door is unlocked.
NOTE: Automatic door locking mechanism keeps chamber
locked during entire Biodecontamination Cycle.
