Clean Room Equipments

Fan Filter Unit Laminar Flow Units

Laminar Flow Cabins with FFU's is made of special aluminum profiles and stainless steel frames. Cabins are either designed to be hanged from ceiling or comes with rolling wheels. Transparent curtains, velocity control switch, magnehelic monometers are some of the accessories.

Fan Filter units achieve Class 100 conditions according to U.S. Federal Standard 209E or ISO Cl ass 5 according to ISO 14644-1:1999 with speed controlled fans, pre-filter (G3) and HEPA filter (H14). Clean-air velocity is about 0,45 m/s (±%20) measured 15-20 cm under the air distributor.

Laminar flow cabins with FFU supplies laminar flow achieving positive pressure in the cabin. These models are used only for laminar flow purpose. They can be designed any dimension according to the demand.

 

Laminar Flow Cabins for Weighing & Sampling

Process type laminar flow cabins are used for production, weighing, sampling and packaging. These laminar flow cabins consist of prefilters, fans, HEPA filters (H13/14), lightning fixtures, electric and automatic control systems, PVC curtains,wheels or parts for hanging from ceiling. At below, you can find reference pictures of process type laminar flow cabins. According to the applications optional accessories like cooling coil, temperature and humidification monitoring can be supplied.
 

 

Microbiological Safety Cabins

Paslanmaz çelik konstrüksiyon, paslanmaz gövde ve 304 kalite paslanmaz çelik çalışma tablasının bulunduğu çalışma alanında 1 adet kapalı sistem topraklı priz ve ultraviole lamba bulunmaktadır. Sistemde üfleme ve egzost havasında olmak üzere 2 adet H14 sınıfında 0,3 µm büyüklüğündeki partiküllerin tutulması için %99,999 verimlilikte HEPA Filtre bulunmakta ve bu filtreler ön filtre ile korunmaktadırlar. Bu filtrelerin test edilmesi amacıyla %100 konsantrasyon için DOP test çıkışı bulunmaktadır. Üfleme havası çıkışında bulunan bir sensör yardımıyla hava hızı ölçülerek dijital ekrandan izlenebilmekte ve bir potansiyometre yardımıyla hava hızı istenilen seviyede tutulabilmektedir.

Mikrobiolojik emniyet kabinleri; negatif ve pozitif basınçlı olmak üzere ikiye veya Klas 1, Klas 2 ve Klas 3 olmak üzere 3 gruba ayrılır.

HEPA Filter Boxes

Main demands of the clean room technology and especially in its pharmaceutical applications is the air-conditioning and also accordingly the air quality. Air distribution is generally made through the HEPA filter installed to its housing. Therefore, selection and assembling the HEPA filter to its housing without leakage is very important. Tetisan HEPA Filter Housing consists of 3 main parts, which are the box, filter and the diffuser. Box has a duct connection port for air inlet at the top or at the sides. On the room side the diffuser can be selected either with special vanes adapted to cleanrooms or with a perforated plate. Filters can be chosen according to the room Class from H10 to H16. HEPA Filter Boxes weighs between 12 kg and 47 kg according to the construction type. All HEPA Filter boxes are tested for leakages with test groove system.

 

To track filter working conditions, HEPA boxes have nozzles for differential manometer connections. According to the EN 1882 standards, boxes have nozzles for supplying test aerosols (DOP). Test grooves that face the HEPA filter gasket achieves air tightness according to DIN 1946 Part 4. Inside of the housing can be easily disinfected and will not be effected from disinfection chemicals.
