Internal Size:  1300x600x650mm 
Purification rank: Class100
Display : Led display  control
ULPA filter efficiency:99.995%@0.12um

Vertical Laminar Flow cabinets station combines several of our most advanced products in a state-of-the-art work station that removes particulate air-borne contamination. The backbone of the system is the reliable Filter/Fan Unit (FFU), which provides a flow of microfiltered air to meet cleanliness standards. Patented baffling technology ensures uniform airflow across the filter face and attenuates sound for the lowest noise level in the industry: approximately 50 dBA .Select the ULPA  filter, rated 99.9995% efficient removing 0.12-micron particles. Each unit includes a high/medium/low adjustment switch. 



Laminar flow cabinet is widely used in medical research laboratories, hospitals, manufacturing
facilities and other research and production environments.

Operating features:
 A:ISO Class 4 air cleanliness within work zone as per ISO 14644.1 (Equivalent to Class 10 as per US
     Federal  Standard 209E,10 times "cleaner" than the usual Class 100 classification on clean benches
     offered by the competition).
 B: High-quality polyester pre-filter and main ULPA filter with a typical efficiency of 99.9997% at MPPS and
      99.9998% at both 0.3 and 0.12 microns provide the best product protection in the world; typical main
      ULPA  filter lifespan is more than 3 years depending on the usage of the clean bench.
 C:Mini-pleat separatorless ULPA filter technology reduces energy consumption and delivers increased
      laminar airflow uniformity for better product and cross contamination protection.
  D: Integral filter metal guard on both sides prevents accidental damage to ULPA filter; seamless filter
       gasket is permanently molded on the filter frame and will not deteriorate over time; aerosol (DOP/PAO)
       challenge test port included.
  E: American Dwyer pressure remind of you replace the ULPA air filter in regular.
