Deep-Pleat Separator HEPA Filters | Direct Factory Wholesale Solutions
Source Direct From Our Deep-Pleat Separator HEPA Factory Engineered for strict cleanrooms, HVAC systems, and industrial ventilation. As an integrated manufacturer, we deliver heavy-duty, high-airflow H10 to U15 filtration products built with precision aluminum separators and high-grade fiberglass media.

Deep Pleated HEPA filter with separator | H10-U15 High Airflow Ventilation
Ultra-High Efficiency: High-performance fiberglass media (H10–U15) captures 99.9995% of particles (0.12μm) for strict cleanroom compliance.
Optimal Airflow: Precision aluminum separators prevent pleat collapse and ensure uniform airflow, eliminating “dead zones”.
Airtight Reliability: High-grade polyurethane sealant provides full-frame encapsulation, completely eliminating air bypass risks.
Durable Build: Rigid metal alloy frames and premium media ensure long-term structural integrity against humidity and high-pressure impacts.

Customizing Deep-Pleat Separator Filters for Your Projects
Custom Dimensions & Frame Materials: As a direct manufacturer, we offer full customization on filter depth, face dimensions, and frame options for every deep-pleat separator HEPA filter—including aluminum alloy, galvanized steel, and corrosion-resistant stainless steel—to match your exact installation requirements.
Comprehensive Efficiency Tiers (H10 to U15): Support your clients with reliable filtration grades tailored for strict cleanroom classes. Every custom separator HEPA filter batch is backed by rigorous multi-stage testing reports to ensure consistent particle retention.
Reliable Bulk Wholesale & OEM Support: Benefit from stable supply chain management, competitive direct-factory pricing, and specialized OEM manufacturing. Whether you need standard inventory or custom-engineered deep-pleat HEPA filters, we streamline your global sourcing process.
Frequently Asked Questions on Customizing & Sourcing Our Separator HEPA Filters
Q1: What standard and custom sizes are available for separator HEPA filters?
A: We supply standard dimensions such as 24″ × 24″ × 11.5″ and 24″ × 12″ × 11.5″, as well as fully customized separator HEPA filter sizes. You can specify exact face dimensions, frame depths, and media pleat configurations to fit your unique HVAC, cleanroom, or AHU housing requirements.
Q2: What separator materials do you use in deep-pleat HEPA filters?
A: Our deep-pleat separator HEPA filters utilize high-grade corrugated aluminum separators (or paper separators upon request). Corrugated aluminum separators ensure optimal airflow channel uniformity, high structural stability, and resistance against high humidity and pressure differentials in heavy industrial filtration systems.
Q3: How do I select the right efficiency grade and pressure drop specs for my order?
A: We manufacture separator HEPA filters in efficiency grades ranging from H13 (99.95% MPPS) to H14 (99.995% MPPS) tested according to EN1822 / ISO 29463 standards. Our engineering team helps you balance initial pressure drop, airflow velocity (CFM), and particulate capacity during the sourcing phase to ensure maximum system efficiency.
Q4: What frame materials and gasket options are available for custom HEPA filters?
A: To match diverse industrial application environments, we offer frame options including Galvanized Steel, Stainless Steel (SUS304/316), Extruded Aluminum, and MDF Wood. Gasket options include continuous polyurethane foam, endless neoprene, or gel-seal configurations for guaranteed zero-leakage installation.
Q5: What is the lead time, MOQ, and factory quality assurance process for bulk sourcing?
A: As a direct manufacturer, our standard production lead time is 7–14 business days depending on order volume and custom specifications. Every separator HEPA filter undergoes rigorous factory scan testing (DOP/PAO test) and individual efficiency reporting before shipment to meet strict B2B procurement standards.
