These are high in performance are manufactured in conformation to the international standards using various filters like HEPA and different clean room accessories. Our equipment finds wide application in Pharma, Medical, Aerospace, Microelectronics etc. We also offer Annual Maintenance Contract & Service for these systems along with Calibration & AMC that comprises of Service and Validation. Our credible service and unmatched quality range is widely appreciated and is in high demand all across the country. Our all-encompassing range includes the following:

Laminar Flow Workstation

A Laminar Flow Unit is a sub-micron air filtration equipment that provides Sterile/Clean environment on a small area/zone such as a Table Top or a filling area. Laminar Flow Units protects the product from being contaminated by engulfing the entire product in Class 100 atmosphere. Airflow could be Horizontral flow or Vertical flow depending the direction of air flow. Our Horizontal Laminar Flow Unit is called benchMARK and Vertical Unit is called standMARK.

These equipments essentially have a HEPA filter, a Pre-filter and a Blower with a enclosure to house all these and a work area where the critical operation takes place. Depending on the requirement of clean air flow the type of unit is selected.

Laminar Airflow Unit protects only the product and not the person or the environment, so Pathogenic work/hazardous work should not be done in this system.

Application: Pharma - Filling, QC, Microbiology, Micro-electronics & Electronic Assembly, Patient Care, Andrology & In-vitro Fertilization, Biotechnology/Tissue Culture, Optics, Electro-optics, Aerospace, Defense & Nuclear Research

Biological Safety Cabinets

Biological Safety Cabinets are safety equipments to be used for handling Hazardous Pathogens. These cabinets, apart from creating a Clean & Sterile environment, to protect the product/sample also protects the Lab personnel and the Atmosphere.

The vertical downward airflow protects the product, the inflow along the front edge protects the user and the HEPA filtered exhaust air protects the atmosphere.

Pathogens have been classified into four risk levels from 1 to 4. Based on the level of risk of the pathogen and the procedure, NSF-49 of USA has classified the Biosafety cabinets into three Classes viz. Class I, Class II & Class III.

Class II cabinets are further classified into 3 types viz. Type A/B3, B1 & B2.

Class II Type A/B3 recirculates 70% air and exhausts 30% air
Class II Type B1 recirculates 30% air and exhausts 70% air
Class II Type B2 exhausts 100% air without recirculation.

HEPA Filters

HEPA fitlers or HIGH EFFICIENCY PARTICULATE AIR filters are made of 100% glass microfibre. These filters remove 0.3micron and larger particles at a minimum efficiency of 99.97%. First Air coming out of a HEPA filter is Class 100. HEPA filters are used in applications where a Dust free and Sterile Environment is required. These filters have a high pressure drop of the order of 250Pa, so high static pressure blowers are required for overcoming the pressure drop.

As HEPA filters remove sub-micron particles and as the HEPA filter media is delicate, these can get damaged even while storing. To ensure that the HEPA filters installed in the equipment/AHU are not damaged, there are certain tests that have to be done. These tests are Air velocity checking, HEPA filter Pressure drop test & HEPA filter Integrity Test (DOP Test)
HEPA filter Integrity test procedure: the filter is challenged with known aerosolized particles of 0.3micron and larger (DOP, POA etc)on the upstream side and checked downstream using a Photometer Probe. If there is a leak in the filter, the particles are sensed by the scanner of the Photometer and displayed as leak on the LED screen. If the leak is more that 0.03%, the filter is supposed to have failed.

While procuring HEPA filters it should be insisted that the supplier has a HEPA filter testing facility and ensure that the filter is tested onsite after installation.

As more than 95% of the HEPA filter media used in India is imported and expensive, to prevent frequent replacements, always a pre-filter has to used before HEPA to filter the coarse particles.

These are designed based on air quantity. Two types of HEPA filters are available, one is Aluminium Separator type and the other is the State-of-the-art Minipleat type. Minipleat HEPA filter is more sleek than the Separator type HEPA.

In Clean Rooms HEPA filters are installed in the Air Handling Unit or in the specially designed Terminal Plenum. Apart from Clean Rooms HEPA filters are used in Lab Equipment employing Air filtration such as Laminar Flow Workstations, Biological Safety Cabinets, Air Showers, Positive Pressure Modules etc.

Pressure Modules - Critical Rooms

Clean Room Modules are HEPA filtration systems that cater to the "Small Clean Room" requirements of Clients who work on a limited budget and for applications where a full fledged Clean Room, involving major site alterations and costs is not possible or not necessary. To meet these requirements, MARK has developed HEPA filter Modules each of the modules has a specific purpose as detailed below.

The Positive Pressure Module feeds fresh air into the room after HEPA filtration, the Room Air Dilution Module recirculates room air through the HEPA filter in repeated cycles resulting in dilution of the concentration of contaminants / particulate matter in the room, the AC connectable Module filters the cooled air from the window air conditioner in a HEPA filter and supplies sterile air to the room.

A combination of the modules described above helps in achieving the desired cleanliness level in the room.

Note : Modules are suitable for rooms that are not wider than 12ft., in wider rooms air distribution might be affected.

Clean Rooms - Class 100K to Class 100

Clean rooms are special temperature controlled rooms where Temperature, Relative Humidity and Particle Count are regulated. In order to attain and maintain the desired conditions in the room, Air Conditioning is Integrated with Air Filtration.

Air Filtration takes place at sub-micronic levels, 0.3micron level to be precise, at a very high efficiency of 99.99%. To prevent contaminants from entering the room, the room is maintained at a positive pressure relative to the adjacent rooms.
