Biological Safety Cabinet HR900-IIA2

Patent Intelligent Constant Air Velocity

The professional hot-bulb air velocity transducer performs real-time monitoring on the air velocity of the working area compares it with the standard air velocity and keeps the safety cabinet under constant air velocity through adjustment of the fan speed by microcomputer system

Professional Air-flow Distribution Module

Through professional air flow distribution design，the air flow of the worktable is more uniform，with the noise＜62dBA

LNS Green Energy-saving Mode

When the human body detecting module detects under the intelligent mode that the person is outside the operating area for 15 minutes，the microcomputer program will automatically switch the cabinet to LNS green energy conservation mode，so as to realize noise reduction and energy conservation and to improve the service life of the filter

Ultra Low Penetration Air Filter System

Camfil （ULPA）filter are tested to a typical efficiency of ＞99.999% for 0.12 micron particles. ULPA Filter provides vertical laminar flow to the workable，so as to protect samples from pollution

Patent Technology of Air Flow Disruption

Adopt the patent technology of air flow disruption on the upper edge and both sides of the front window (Patent No. ZL200520125549.X) to eliminate the safety protection blindness. Adopt the patent technology of side air flow disruption design to eliminate the exposure of microorganism.

Unique Drop-down Front Glass Window

Remove the hand-placing frame by hand, and pull down the front glass window to clean the upper part of the glass and to avoid dead corners.

Dismountable Platform-type Hand-placing Frame

Platform-type hand-placing frame is comfortable to use and helps to relieve fatigue.

304 Stainless Steel Operation Platform & Internal Wall

• Stainless steel operation platform without screws, no accumulation of contaminant
• Dismountable air in-flow plate, easy to clean and disinfect
