Mark Air Particulate Control Systems

Our Fan Filter Units (FFU) are silent performers. With our FFUs Cleanliness levels of upto Class 10 can be achieved. We have 4 standard sizes of FFUs, 48" X 24" X 14", 36" X 24" X 14", 24" X 24" X 12" & 18" X 18" X 10"

We use imported state-of-the-art compact blowers from Germany in these FFUs. These are designed, fabricated and tested in world class factories. The Motor-Blower assembly is fully balanced and designed for continuous operation. HEPA filters are minipleat type with micro-fiberglass media to trap submicron particles of the range of 0.3microns at a very high efficiency.

These FFUs are versatile in application and can be integrated to various types of HVAC systems. We use these FFUs in Modular Clean Rooms for Terminal HEPA filtration, as hook-up modules for Clean Room upgrades, Softwall & Hardwall Clean Rooms, Laminar Flow Units, Positive Pressure Modules.

The FFUs can be connected to ducts in Clean Rooms or can be installed on stands & be called a Clean Tent or a Laminar Flow Unit. The FFUs are very sleek and can be easily hidden above the false ceiling or in a T-grid so that the HEPA filter is only visible from the Clean Room.

To suit all Site requirements, our FFUs are designed with Room Side Replaceable (RSR) HEPA filters, non-RSR HEPA filters, RSR HEPA & Blower etc. For Modular Clean Rooms a specially designed control panel is supplied with the FFUs on request with speed control & monitoring options.

These FFUs are used in all Lab applications such as Microbiology, Biotechnology, Mushroom-inoculation, Medical Diagnostics, College Research (PhD), Display panel assembly & service - TVs, Mobiles, Tablets etc, Microelectronics, PCB testing/service etc. Animal House, Dust control, Plant Tissue Culture, Pilot plants for Pathogen control etc.

We have a fully equipped and trained installation & service team with all the necessary instruments such as Aerosol Photometer, Particle Counter, Air Velocity-Anemometer etc. all calibrated to NABL traceability. We undertake AMC and Validation/Calibration of all HEPA filtration systems including FFUs.

Sterile Rooms are the same as Clean Rooms. These rooms are not only dust free but also micro-organisms free. These rooms are defined as per international Standards such as US Federal Standard 209E or ISO-14644-1.

Based on the requirement of the Client and his application, we design suitable systems to achieve the desired conditions such as Temperature, Relative Humidity, Cleanliness level etc. in the Clean Room. The desired conditions are achieved by integration of Air-conditioning and filtration.

Filtration takes place at sub-micron level, at 0.3microns level to be precise at a very high efficiency of 99.99%. For the a certain level of Cleanliness to be achieved in a room a certain quantity of air has to be supplied to the room through HEPA filters.

The air entering the room after HEPA filtration is better that Class 100 clean. This air is already cooled and conditioned in the Air Handling Unit to achieve the temperature and RH in the room. The Class 100 air that enters the room, fills the room and carries with it the suspended partlcles and pushes the settled particles at the floor level to the corners of the room, where Return Air Risers are installed to carry the contaminated air to the AHU for reprocessing. 

Though the room condition, mainly the Cleanliness level, is achieved by the AHU and HVAC systems, it can be sustained only by having proper interior finishes in the room.

In Modular Clean Rooms the Wall and Ceiling Panels are designed in such a way that they do not shed particles, contaminant/dust collection is minimum and cleaning is easier.

In Conventional Clean Rooms Wall has to be smoothened with Putty and fully coated with Epoxy/PU to make it non-shedding and impervious.

False Ceiling has to be made of rigid material and suspended from the RCC roof and made air tight, so that the positive pressure in the room does not bring down the particles above the False Ceiling. All 90deg. joints between wall-wall, wall-floor & wall-ceiling are rounded off with masonary Coving or Epoxy Coving to facilitate cleaning.

Floor should be seamless, without joints with smooth finish. Poured Epoxy or PVC floor with welded joints is preferred.

The Air Shower equipment available with us is a self-contained Clean Room entry enclosure that minimizes the entry of particulate contaminants carried by the personnel entering the Clean Room. The first air is better than Class 100. We fabricate Air Showers to suit your requirements, though we have standard sizes.

Working of the Air Shower:

Air Shower is a double door enclosure, one door for entry to the enclosure and the other, the exit door that leads to the Clean Room. The Shower is equipped with high static blowers that discharges HEPA filtered air at high velocity in the order of 3500 feet per minute through nozzles located on the ceiling and walls of the enclosure. As the HEPA filtered ultraclean air strikes the person(s) from all directions, at high velocity, it dislodges lint/dirt/contaminants that hang loosely from the garment or exposed body parts. These particles are thrown to the floor of the enclosure and sucked by the blower through Pre-filters.

A solid state electronic circuit renders the operation fully automatic & controls the sequential operation of the Electromagnetic door interlock arrangement. This ensures entry of personnel only after the air shower.

uni directional streams of class 100/zero cfu air sweep through the work area to render it ultraclean and sterile .the inputs that go into the making of these systems are of the highest quality standard recommended by reputed international bodies such as the institute of envirorment sciences (ies),usa 

Sterile Garments can be stored in our Garment Storage Cabinet, the Cabinet storage space is maintained sterile by HEPA filtration. For additional sterilization, an Ultra-Violet Lamp is also installed. For hanging Garments, a rod is provided at the top. A double door with locking arrangement is provided. Optional racks are available for stacking the Garments or for storing other Clean Room tools and material.
