Page 8: General Description
INTRODUCTION General Description The Labconco Purifier® Vertical Clean Bench is a HEPA (High Efficiency Particulate Air) filtered ventilated enclosure designed to provide product protection from airborne particulate matter. Each Clean Bench uses a single HEPA filter, which has been tested at the factory to be at least 99.99% efficient for particles 0.3 micron. -
Page 9: Performance
INTRODUCTION Performance During operation, room air is drawn through the prefilter on the top of the Vertical Clean Bench. The motor/blower(s) force this prefiltered air into the HEPA filter, and the velocity of the HEPA filtered air is stabilized by a diffuser located at the top of the work area. The clean air in the work area meets or exceed Class 100 conditions as defined by Federal Standard 209E, and the motor/blower speed control is factory set to deliver an average nominal airflow of 60-80 feet per minute. -
Page 10: Component Identification
INTRODUCTION Component Identification – See Figure 3 1. Speed Control. The solid-state speed control regulates the speed of the motorized impeller. 2. Motorized Impeller. The Safety Enclosure is equipped with a variable speed motorized impeller. The impeller wheel is dynamically balanced for low vibration and noise, and the low wattage requirements of the permanent split capacitor (PSC) motor reduces operating costs. - Page 11 INTRODUCTION Component Identification Figure 3...

HEPA filter during installation or normal operation. If you suspect that a HEPA filter has been damaged DO NOT use the Clean Bench; contact a local certification agency or Labconco at 800-821-5525 for recertification information. The HEPA filter in the Purifier Vertical Clean Bench will gradually accumulate airborne particulate matter from the room and from work performed in the Clean Bench. - Page 16 SAFETY PRECAUTIONS NEVER place items on top of the Clean Bench. They may block or restrict the intake opening on the top of the cabinet, affecting its performance. When surface disinfecting the Purifier: Avoid splashing the disinfecting solution on skin or clothing. Ensure adequate ventilation.
