Designed exclusively for high-demand cleanroom environments and industrial air purification systems, the Durable 380 Air Filter integrates robust construction, large airflow capacity, and specialized glass dust filtration-paired with a built-in air regulator to optimize air distribution. Engineered to work seamlessly with Cleanroom Fan Filter Units (FFUs) (critical for maintaining ISO 14644-1 Class 5 to Class 8 cleanroom standards), this filter delivers consistent, high-efficiency particle capture while withstanding the rigors of 24/7 operation in electronics manufacturing, pharmaceutical production, laboratory research, and other contamination-sensitive settings. Its "durable 380" designation refers to its 380mm standard dimension (configurable to 380x380mm, 380x610mm, etc.) and enhanced structural resilience, making it a reliable core component for large-airflow cleanroom ventilation.
I. Core Filtration Performance: Specialized for Glass Dust & Fine Particles
Multi-Stage Filtration for Cleanroom-Grade PurityThe filter features a two-in-one composite structure tailored to address both coarse contaminants (e.g., glass dust, machining debris) and fine particles (sub-micron dust, aerosols):
Pre-Filtration Layer: A high-density synthetic fiber pre-filter (MERV 8-10 per ASHRAE 52.2) captures large particles like glass dust (common in display panel manufacturing or optical component production), coarse dust, and fibers. This prevents premature clogging of the main filter and extends overall service life.
High-Efficiency Main Filter: Available in H13 or H14 HEPA grades (per EN 1822:2019) or F7-F9 medium-efficiency grades (per EN 779:2012), the main filter achieves 99.95%+ efficiency for particles ≥0.3μm (H13) or 80-95% efficiency for particles ≥1.0μm (F9). It effectively removes fine glass dust residues, mold spores, bacteria, and other micro-contaminants that could compromise cleanroom processes (e.g., semiconductor wafer fabrication, pharmaceutical sterile filling).
Large Airflow Capacity for FFU CompatibilityOptimized for Cleanroom FFUs-devices designed to deliver high-volume, uniform airflow (typically 100-150 CFM per unit)-the filter features a pleated media design with an expanded effective filtration area (3-4x larger than flat-panel filters of the same size). This design enables it to handle airflow rates of 800-1,200 m³/h (470-706 CFM) with a low initial pressure drop (≤200 Pa for H13 grade at rated airflow). The large airflow capacity ensures FFUs maintain consistent air changes per hour (ACH)-critical for cleanrooms (e.g., Class 5 cleanrooms require 240+ ACH)-without straining the FFU fan or increasing energy consumption.
II. Durable Construction for 24/7 Cleanroom Operation
The "durable" designation is reinforced by premium materials and structural design, ensuring reliability in continuous-use cleanroom environments:
Rigid Frame for StabilityThe filter frame is constructed from 1.2mm-thick galvanized steel or 5052 aluminum alloy (optional for corrosion-sensitive settings). Both materials resist deformation, vibration (common in FFU arrays), and temperature fluctuations (operating range: -20℃ to 80℃ / -4℉ to 176℉). Unlike lightweight plastic frames, the rigid structure prevents media sagging or frame warping-even under high airflow pressure-maintaining consistent filtration performance over time.
Reinforced Media BondingThe filter media (pre-filter + main filter) is securely bonded to the frame using high-temperature-resistant adhesive (rated up to 120℃ / 248℉). This eliminates media detachment-a common failure point in low-quality filters-and prevents unfiltered air from leaking through gaps. The adhesive also resists chemical exposure (e.g., mild cleaning agents used in cleanroom maintenance), ensuring long-term structural integrity.
Airtight Sealing for Zero BypassA full-perimeter EPDM rubber gasket (3-5mm thick) is integrated into the frame's sealing edge. The gasket compresses tightly against FFU housing when installed, creating an airtight seal that eliminates "bypass air" (unfiltered air leaking around the filter). This is critical for cleanrooms, where even 0.1% bypass air can push particle counts above ISO standards.
III. Built-In Air Regulator: Optimized Air Distribution
A key differentiator of this filter is its integrated air regulator-a precision damper or louver system built into the filter's outlet side-designed to solve a common challenge in FFU arrays: uneven airflow across large cleanroom floors.
Precision Airflow ControlThe regulator features adjustable blades (manual or motorized, optional) that allow fine-tuning of airflow velocity (typically 0.3-0.5 m/s, the recommended range for cleanrooms) in specific zones. For example, in a semiconductor cleanroom, areas near wafer handling equipment may require higher airflow to prevent particle accumulation, while adjacent storage zones can operate at lower velocities-all controlled via the filter's built-in regulator.
Reduced TurbulenceThe regulator's aerodynamic design minimizes airflow turbulence as air exits the filter, ensuring uniform air distribution across the cleanroom ceiling (a critical factor for maintaining laminar or turbulent airflow patterns required by different cleanroom classes). This reduces "dead zones" where particles could settle, enhancing overall cleanroom air quality.
IV. Key Advantages for Cleanroom & Air Purification Systems
Extended Service Life, Lower MaintenanceThe multi-stage filtration design and large dust-holding capacity (≥350g/㎡ for H13 grade) extend the filter's service life to 6-12 months (depending on cleanroom dust load)-20-30% longer than standard FFU filters. This reduces the frequency of filter replacements, minimizing cleanroom downtime (critical for 24/7 operations like pharmaceutical manufacturing) and lowering maintenance labor costs.
Energy EfficiencyThe low initial pressure drop (≤200 Pa) and large airflow capacity reduce the workload on FFU fans, cutting energy consumption by 8-12% compared to high-resistance filters. The integrated air regulator further optimizes energy use by avoiding over-ventilation in low-demand zones.
Compliance with Cleanroom StandardsThe filter meets global cleanroom and safety regulations, including:
EN 1822:2019 (HEPA/H13 classification)
ISO 14644-1 (cleanroom air quality compatibility)
FDA 21 CFR Part 111/117 (pharmaceutical/food contact safety)
RoHS (restriction of hazardous substances, ensuring no toxic materials leach into the cleanroom environment).
