The Pure Air Systems 600 HEPA Series is the first whole-house certified HEPA filtration system and the last system you will ever need. By utilizing the efficiency of HEPA filters, the 600HS has adopted the same filtration effectiveness as required in hospital surgery rooms, clean rooms, and other applications where the removal of harmful respirable particles (less than 1 micron in size) are necessary.

Commercial-Grade HEPA Filtration

The 600HS, like all of our systems, use a three – stage filtration process. Each unit includes a commercial grade dual-layer polyester ring panel filter that is used to remove the larger particles and protect the carbon and HEPA filters. A 5lb pad of carbon media is included for removal of gases and odors. The final filter is a true, commercial grade, certified 99.99% at 0.3 microns metal framed HEPA filter.

Variable Speed Motor

The 600HS PLUS is using a GE (Genteq) ECM variable speed 120/240 volt, 50/60 Hz energy efficient 1/3 HP motor. The ECM motors can use 40% – 50% less energy to operate than a standard induction motors. The 600HS unit provides over 600 CFM of HEPA filtered air.

Attach to Any HVAC System or Use as a Stand-Alone Unit

The 600HS unit was designed to be used either attached to any forced air ducted heating/cooling system or used as a stand alone unit. In either case, installation must be performed by a certified professional. Units are available in a variety of configurations for individual applications. Please contact us to discuss your specific needs.

Horizontal and Vertical Configurations – “L” and “S” Versions

For attachment to a ducted heating/cooling system typically the “L” version of the 600HS unit is used. The “S” unit, or straight through unit, can also be used for attachment to HVAC units when the “L” version is not suitable. Either the “L” or “S” versions can be used as stand-alone systems when not using an HVAC unit. The “L” or vertical housing allows for left or right hand installation and the “S” or horizontal unit allows for ceiling mount or attic installations.

The 600HS “L” and “S” series units are manufactured using a unique split housing design where the blower/motor section and filter section are separate but symmetrical. This allows the top and bottom sections to be rotated in any of four positions to allow for best inlet or discharge configurations. This also allows for best access to the filter section via the filter access door.

Controller for the 600HS PLUS Series Units

HVAC Controller

If the 600HS unit is used attached to an HVAC unit either a sail switch or pressure switch can be used to operate the 600HS in conjunction with the heating/cooling thermostat. For all other applications the on/off switch can be used. Pure Air Systems offers two different controller options for the PLUS series. Couple the ECM motor with our HVAC controller and the system fan will modulate (speed up and ramp down) in conjunction with most heating/cooling systems.

VCU Controller

For applications where more flexibility in HEPA filtered air volume control is required or you want to run the system independently you can use the VCU controller. The digital VCU controller allows for air flow speed control from 1 to 100% of volume in 1% increments.

BCU (Bluetooth) Controller

The BCU speed controller allows you to adjust the speed from 0 – 100% in 1% increments. The app shows the speed in percent of air volume capacity.
