The NCF600 Negative Air Machines are designed for indoor use and provide the most efficient air filtration with three stages of filtration. The final stage includes a HEPA (High-Efficiency Particulate Air) filter that can remove 99.97% of particles 0.3 micron or larger from the air. For portability, each unit is equipped with two handles and four rolling casters. The two speed motor is thermally protected and powers the three stage filtration process. The units are independently tested and backed by a one year limited warranty.
SPECIFICATIONS
• Housing - galvanized steel
• Power
- 115 volts
- 60 Hz
- 1625 rpm
• Motors - 1/2 HP (5 amps)
• Exhaust - 12” diameter
FIRST STAGE — PRE-FILTER PAD
• 16” x 16” x 1” — 1-Ply Pad
• Removes large particles up to 10 microns and larger from the air flowing through the unit, thereby preventing premature loading of the second stage and HEPA filters. The pre-filter pad is recommended to be changed as it becomes loaded and the airflow capacity of the unit decreases—or the pressure gauge at the control panel exceeds 2.6 inches at high speed or 1.9 inches at low speed, of W.C.
SECOND STAGE — RING PANEL
• 16” x 16” x 1” — 2-Ply Ring Pane
• Removes particles up to 1 micron and larger from the air flowing through the unit, thereby protecting the more expensive, HEPA filter. The ring panel filter is recommended to be changed as it becomes loaded and the airflow capacity of the unit decreases—or the pressure gauge at the control panel exceeds
2.6 inches on high speed (1.9 inches on lowspeed) of W.C..
THIRD STAGE — HEPA
• 16” x 16” x 6” - 99.97% Wood Frame HEPA Filter
• Removes smaller contaminated particles up to 0.3 microns from the air flowing through the unit and has an efficiency rating of 99.97%. The HEPA filter is recommended to be changed as it becomes loaded, the airflow capacity of the unit decreases, and the pressure gauge at the control panel exceeds 2.6 inches on high speed (1.9 inches on low speed) of W.C.
