Common Purification Equipment for Cleanrooms

1. Air Supply System Equipment

This category includes Fresh Air Filtration Units, Central Purification Air Conditioners (equipped with primary, medium, and HEPA filtration stages), HEPA Filter Terminals (FFU/HEPA Box), and Pressurization Units.

Central Purification Air Conditioners: Suitable for large public spaces and indoor air purification, providing fresh air, dust removal, and sterilization.

HEPA Filter Terminals: These are the critical terminal filtration devices ensuring cleanliness, primarily used in cleanrooms with a classification below Class 1,000. Our design features a separated structure between the static pressure box and the filter housing to guarantee an airtight seal.

2. Air Return System Equipment

Key components include Return Air Grilles, Primary Filters, and Medium Efficiency Return Air Boxes.

HEPA Filter Terminal Specifications: The housing is fabricated from high-quality cold-rolled steel with bent and welded construction, finished with electrostatic powder coating.

Diffuser Options: Flat or diffusion-type outlet diffusers.

Inlet Options: Top inlet or side inlet configurations.

3. Buffer Zone Equipment

Essential items for buffer areas include Electronic Interlock Doors, Clean Storage Cabinets (primarily for storing cleanroom garments in buffer or auxiliary rooms), and Air Purifiers.

4. Personnel and Material Access Equipment

Air Showers & Cargo Showers: Installed between clean and non-clean areas, these remove dust and contaminants from personnel and goods, effectively blocking pollution sources.

Variations: Available for personnel or cargo; blowing modes include single-side, double-side, and top blowing.

Door Options: Manual, automatic, or rapid roll-up doors.

Function: The front and rear doors feature electronic interlocks, acting as an airlock to prevent unfiltered air from entering the clean zone.

Pass Boxes: Used for transferring small items between clean zones or between clean and non-clean zones to minimize door openings and cross-contamination.

Features: Full stainless steel construction with integrated arc corners for easy cleaning (no dead spots); electronic interlocks with microcomputer control; optional embedded double-layer tempered glass doors; optional differential pressure gauges to monitor HEPA filter status; optional UV sterilization with timing functions.

Applications: Widely used in electronics, micro-technology, biological labs, pharmaceuticals, hospitals, and food processing.

5. Local High-Cleanliness Equipment

Includes Vertical Laminar Flow Workbenches, Fan Filter Units (FFU), Clean Booths, and Self-Cleaners.

6. Other Auxiliary Equipment

HEPA Filters: Designed to capture particles and suspended matter under 0.5um using ultrafine glass fiber filter paper. Types include partitioned (with separator), partitionless, high-air-volume, and ULPA filters, typically used at the cleanroom terminal.

Weighing Booths: Specialized for the pharmaceutical industry (weighing and dispensing). Vertical unidirectional airflow circulates in the main work area to control powder spillage and airborne particles, preventing cross-contamination and protecting both the environment and personnel.

Cleanroom Doors: Includes full stainless steel, full steel, aluminum-framed, and automatic sliding doors. Custom designs are available with square or oval windows (single or double-glazed). Automation options like foot switches and motion sensors facilitate access for medical staff and patients while reducing cross-infection risks.

Miscellaneous: Purification storage cabinets, stainless steel double sinks, assembly workbenches, etc.
