CONVENTIONAL HEPA FILTERS (0.3 µ) :-
Conventional HEPA
(High-Efficiency Particulate Air) filters are the gold standard for high-purity air
filtration in HVAC systems, designed to capture at least 99.97% of particles as small as 0.3
microns. Often referred to as "deep-pleated" or "box-type" filters, they are built for
durability and high dust-holding capacity in demanding environments.
Key Benefits
-
Exceptional Air Purity: Removes allergens, mold spores, soot,
and sub-micron particles that standard filters miss.
-
High Dust Holding Capacity: The deep-pleat design allows for a
longer service life (typically 1–5 years depending on the environment) compared
to thinner filters.
- Pathogen Control: Highly effective at capturing virus-sized
particles (around 0.1 microns) through mechanisms like diffusion and
interception.
Technical Specifications
-
Filtration Efficiency:
- Standard HEPA: Traps ≥ 99.97% of particles at 0.3 µm
(MPPS).
- Medical Grade (H13/H14): H13 offers ≥ 99.995% efficiency,
while H14 reaches ≥ 99.9995%, providing a 10x higher retention rate.
-
Filter Media: Dense mat of borosilicate glass microfibers in a
random web pattern.
-
Construction: Deep pleats (6–12") with corrugated aluminium or
paper spacers.
-
Frame Materials: Options include Aluminium Alloy or Stainless
Steel.
- Sealing: Polyurethane (PU), Neoprene, or Gel-seal gaskets to
prevent "air bypass".
COMMON APPLICATIONS
🏥 Healthcare
Critical for operating rooms,
isolation wards, and ICUs to eliminate airborne pathogens like bacteria and
viruses.
🏭 Industrial Manufacturing
Essential in semiconductor
fabrication, pharmaceutical labs, and aerospace assembly to protect sensitive
processes.
💨 Specialized HVAC
Integrated into AHUs for labs and
cleanrooms, following pre-filters (MERV 8-13) to extend the HEPA's lifespan.
