• Turbulent flow
• Negative pressure mode

Turbulent Flow - Commonly used for 'C' and 'D' classes of cleanliness where the direction of airflow is not clearly defined. The air flows in an irregular direction from the air supply inlet to the air outlet through cylindrical HEPA filters H14 at a filtering efficiency of 99.995%. The rate of air exchanges of clean air into the chamber usually ranges from 5 to 40 exchanges per hour.

The HVAC system allows for the formation of negative pressure in the interior of the isolator. This function is mostly used in case of a failure – compromised leak-proofness - and helps to protect personnel. Another level of protection for critical points in the process is the creation of a pressure cascade so that the location of dangerous substance handling contains the highest level of negative pressure. This minimizes the risk of contaminating other chambers or the surroundings. In order to prevent damage to the equipment caused by insufficient pressure a pneumatic valve is used. This protective function prevents the pressure from dropping further, thus protecting the technology from damage.

Standards

• Cable glands - Cable glands are mounted in the isolator wall.
• Sockets for additional equipment power supply - Sockets are placed on the isolator rear wall. Sockets are operable from the control display. Sockets available in all country variants.
• Wire trays & accessories - The rear panel can be fitted with wire trays and hangers made of AISI 316L stainless steel.
• Built-in LED lights - Built-in LED lights ensure illumination levels of at least of 500 lux.

Safety Features

• Pressure fuse - The pressure fuse serves as a safety element indicating increased pressure in the chamber. In the event that the assigned pressure in the chamber is exceeded a pneumatic flap valve is opened and the pressure value is decreased without deterioration of internal atmosphere.
• Safety glass - We use tempered safety glass for the front windows and ports of our equipment. This glass has improved mechanical properties and is durable. When damaged it forms small chunks which reduce the risk of injury from cuts.
• Safe replacement of sleeves - Our glove / sleeve flanges have two grooves. The first for sealing the glove and the second for an o-ring. This design allows a standardised procedure for the safe replacement of gloves.
• Independent UPS power supply - An independent UPS (Uninterruptible Power Supply) can be installed inside the isolator. In the event of an interruption in the supply of electricity, short-term operation is maintained through a power supply in the isolator to allow the process and the environment to be secured.
• Safe replacement of the main filter
