Phoenix Mini-Guardian HEPA System

TS-261B

The Phoenix Mini-Guardian HEPA System is the compact, variable 
air speed version of our popular Phoenix Guardian HEPA System. 
Maximum delivered air flow with 3-stage filtering in place is over 
45 CFM and will clean one air change of a 4 x 4 foot room in 
less than four minutes while drawing less than two amps of power. 
This makes the Mini-Guardian HEPA System perfect for smaller 
remediation projects where space is at a premium and reduced air 
flow essential. A template on the intake grill makes it possible to 
take air-flow measurements with the Phoenix Kestrel 3000 Multi-
Meter.

The Mini-Guardian HEPA System’s 3-stage filter design with true 
HEPA filtration will remove virtually all hazardous particles from 
the air and an optional fourth stage filter of activated carbon 
and potassium permanganate will absorb a wide range of odors 
and gases. The unique 24” canister HEPA, manufactured for the 
Phoenix Mini-Guardian HEPA System, contains nearly 200 square 
feet of surface area. This allows maximum air-flow and significantly 
extends filter life.

 The Phoenix Mini-Guardian HEPA System

•  Less than 2 amps
