HEPA/ULPA Filter Unit for Dust Containment Systems

Product Specifications

Technical details and manufacturing context for HEPA/ULPA Filter Unit

Definition

The HEPA/ULPA Filter Unit is a critical component within Dust Containment Systems, responsible for the final stage of air purification. It captures and retains microscopic dust, particulate matter, and other contaminants from the air passing through the system, ensuring clean air exhaust and maintaining the required cleanliness levels in controlled environments. This unit is designed for integration into ventilation or extraction systems where high-efficiency filtration is required. It operates by forcing air through a dense, pleated filter media composed of fine glass fibers or other synthetic materials. Particles are captured via a combination of interception, impaction, and diffusion mechanisms. HEPA filters remove at least 99.97% of particles ≥0.3 microns, while ULPA filters remove at least 99.999% of particles ≥0.12 microns. The unit typically includes a frame made of aluminum or galvanized steel, with polyurethane or silicone sealant ensuring an airtight fit. Separators made of polypropylene or aluminum maintain the pleat spacing. Key parameters to verify for your application include nominal airflow rate (500–2000 m³/h), filter efficiency (99.97–99.999%), initial pressure drop (150–300 Pa), maximum operating temperature (60–80°C), and maximum operating humidity (80–95% RH). Electrical specifications include operating voltage (220–240 V AC, single phase, 50/60 Hz) and power consumption (80–250 W). Noise level ranges from 45–60 dB(A) at 1 m distance. Standard filter dimensions are 610×610×292 mm, with weight between 15–30 kg. The sealing gasket is typically EPDM, and the frame is galvanized steel (stainless steel optional). Always verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

Air is forced through a dense, pleated filter media composed of fine glass fibers or other synthetic materials. Particles are captured via a combination of interception, impaction, and diffusion mechanisms. HEPA filters remove at least 99.97% of particles ≥0.3 microns, while ULPA filters remove at least 99.999% of particles ≥0.12 microns. The filter media is supported by separators and sealed within a frame to prevent bypass. As the filter loads with particles, pressure drop increases, indicating the need for replacement.

Glass fiber media, Aluminum or galvanized steel frame, Polyurethane or silicone sealant, Polypropylene or aluminum separator

Components / BOM

Filter Media Part
The pleated sheet that physically captures and retains airborne particles.

Material: Glass fiber or synthetic microfiber
Frame Part
Provides structural integrity, seals the edges, and allows for secure mounting within the housing.

Material: Aluminum, galvanized steel, or stainless steel
Gasket/Seal Part
Creates an airtight seal between the filter frame and the system housing to prevent bypass leakage.

Material: Polyurethane, closed-cell neoprene, or silicone
Separators
Hold the pleats apart so the media does not collapse and blind itself.

Frequently Asked Questions

What is the difference between HEPA and ULPA filters?

HEPA filters remove at least 99.97% of particles ≥0.3 microns, while ULPA filters remove at least 99.999% of particles ≥0.12 microns. ULPA provides higher efficiency for smaller particles.

How do I select the correct airflow rate?

Select based on room volume and required air changes per hour. The nominal airflow rate range is 500–2000 m³/h. Consult the manufacturer for specific sizing.

What maintenance is required?

Monitor pressure drop; when it exceeds the initial value significantly, replace the filter. Check seals and gaskets for integrity. Follow manufacturer's instructions.

Can this unit operate in high humidity?

Maximum operating humidity is 80–95% RH (non-condensing). High humidity can damage the media, so ensure conditions are within limits.
