ISO14644-1 standards, with overheating protection in order to increase users' safety application. The surface is smooth and bright, lower air resistance and good sound insulation. Special air entrance design and lower the noise effectively.

 Use efficiency increased by 50%: Round air without collision, centrifugal rotating, and tension continuously strengthen, quickly take away the dust particles

Designers carefully designed the diffuser plate to ensure that the airjet speed to prevent the product from create eddy current.

Modular rooms can be assembled, disassembled and relocated.

 It helps to minimize the risk of cross-contamination from the operator's activities, ensuring the safety of both the operator and the samples or products being handled.

1. Adopts polish stainless steel inside, which is flat, neat and wearable. The surface material of pass box is cold rolled steel or stainless steel. 2. Doors in two sides with mechanical or electronic interlock device enable two doors can't be in the open state at the same time. 3. Pass box with special sealing strips to guarantee the airproof.

The two doors cannot be opened or closed at the same time to avoid cross contamination; Has emergency stop device; Automatic door opener/closer

♦FREE DESIGN ♦FACTORY PRICE ♦EASY INSTALLATION ♦TIMELY AFTER-SALES SERVICE

DOP dynamic pass box can act as an air lock to prevent high-pressure leakage into clean room

This design helps distribute the air more evenly across the surface of the HEPA filter, reducing the accumulation of particles and extending the filter's lifespan. 

The way of return air from bottom, dust directly falling as per their own natural gravity. Top of the high-speed wind blowing likes the piston movement, can take the dust away quickly by the bottom elevated floor.

It is 100mm thinner than the ordinary FFU.It has the characteristics of light weight, corrosion resistance, rust prevention and beautiful appearance.

Using leading resistance drain layer technology which allows reasonable airflow distribution inside the clean room , effectively guarantee the indoor cleanliness.

The design is for long distance air supply or discharge, which has advantages of maintenance free, little vibration, low noise and big power air supply. Hanging or floor mounting freely.

Customized design and functions for various application: customized T-shaped, L-shaped, Z-shaped, U-shaped and other shapes, also different materials and components

Stainless steel high-speed airflow nozzles, durability, corrosion resistance, easy cleaning and maintenance, high hygiene standards, and compatibility with various disinfection agents.

It has the advantages of small vibration, filter replacement reminder, maintenance-free, and corrosion resistance.

Two-doors electronic interlock to prevent cross-infection and to achieve sealing requirements, also with infrared probe, transparent window, infrared induction blowing, clear indicator light, emergency stop switch.

Intelligent control. Adjustable blowing time and interlock system. Strong airproof effect. Stainless steel nozzles at three sides and big air volume. Low noise fan.

Adopts the gel mini-pleat HEPA filter with better sealing.

Start-up current is only 1/5 AC fan

Adopt send-off wind system making air velocityis adjustable by touch the switch lightly, which makes the wind speed ideal status.

EFU is used in purification equipment to help them purify the air and ensure a clean environment.
