PRE Filter

PRE Filter Manufacturer

FILTERS are the first stage filtration installed in the AHU to prevent dust particle to pass through air. It has other applications in equipment like Laminar Air flows, Dispensing Booths & other air particle control system. Suitable for use as filter grade GI to G4 of EN779 and MERV 1 to 7 of ASHRAE 52.

Pre-filters are used in manufacturing processes to remove larger particles, contaminants, or impurities from fluid or gas streams before they enter the main filtration system. They serve to protect the primary filters by capturing debris and preventing clogging or damage. Pre-filters can be mechanical, coalescing, cyclonic, or electrostatic, depending on the application. They find use in HVAC systems, water treatment, and various industrial processes. Regular maintenance and replacement are necessary to ensure their effectiveness.

We manufacture top class PRE FILTERS of standard & customized sizes.

Fine Filter

Fine Filter Manufacturer

FINE FILTERS or MICROVEE FILTERS are filters installed in the AHU to prevent dust particle to pass through air. Suitable for use as filter grade F5 to F9 of EN779 and MERV 8 to 15 of ASHRAE 52.

Fine filters, also known as final filters or high-efficiency filters, are essential components of filtration systems used in various industries. Their purpose is to capture and remove smaller particles and contaminants from fluid or gas streams with high filtration efficiency. They can be fibrous filters, membrane filters, or activated carbon filters, depending on the application. Fine filters are used in cleanrooms, laboratories, HVAC systems, and gas/liquid filtration processes.

We manufacture top class Fine Filters of standard & customized sizes.

Air Purifier HEPA Filters

HEPA Filter

HEPA filters are high-efficiency air filters designed to trap 99.97% of particles as small as 0.3 micrometers, including dust, allergens, bacteria, and viruses. They are used in various applications to improve indoor air quality, especially in environments where clean air is crucial, such as hospitals, cleanrooms, and homes.

HEPA filters are made of dense fibrous materials and can be incorporated into air purifiers, vacuum cleaners, HVAC systems, and other devices to remove airborne contaminants. Regular maintenance and replacement are necessary to ensure their effectiveness in trapping particles and maintaining optimal air flow. There are different types of HEPA filters, including True HEPA (meets strict standards), HEPA-type (less efficient), and ULPA (higher efficiency for ultra-clean environments). The use of HEPA filters can significantly benefit individuals with allergies, asthma, or respiratory conditions by reducing exposure to airborne pollutants. Contact us today!
