Clean bench for the pharmaceutical industry ZHJH series

for research laboratoriesfor general purposesinspection

Overview
LABWIT premium vertical flow clean bench is a series of high air purifying equipment with an intellectualized control system to ensure a clean working environment. These units are designed for a particle-free, bacteria-free clean-air environment which is used for laboratory work, testing, manufacturing, inspection or pharmaceutical procedures under ISO Class 5 conditions to prevent airborne contamination. They are economical, lightweight and are available in a variety of sizes. The patented HEPA filter monitoring system features an automatic filter integrity test, called “Self Validation Test”, making sure the HEPA filter is integral and valid, hence the working room is properly protected every time before operation is started.

Operation principle
During operation, room air is drawn through a pre-filter in the top of the cabinet to trap large particles. Air flows through a HEPA filter and is blown vertically over the work area. The positive pressure laminar airflow provides product protection within the work area. The HEPA-filtered air prevents contaminants from entering the work area and provides a particulate-free work environment that minimizes cross contamination.

Features

• Automatic HEPA filter integrity test monitors and alarms against HEPA filter breakage and overloading.
• LCD screen displays the actual speed, differential pressure, flow volume and HEPA status.
• A pre-filter traps large particles to extend the life of the HEPA filter.
• A quiet stepless adjustable speed internal blower provides air velocity.
• Glare free fluorescent lamp.
• Operation mode choices of automatic and manual.
• Standard with high efficiency quartz UV-light.
• Stainless steel work surface.
• Combined base stand with castors.
• Front sash window easy for random positioning.
• Glass windows on left/right side.
• An extra power point is included as standard.
• Time clock display.
