Unlike pure trading companies and assembly factories in the market, SYNRUI's core advantage lies in its 100% self-manufacturing and self-testing of filters (from filter media, pleating, potting to scanning inspection).

SYNRUI possesses independent R&D and structural design capabilities for complete products (FFU, air filter boxes, Laminar Flow Hood, etc.).

All products undergo individual testing for airflow, resistance, efficiency, leakage, and temperature resistance.

SYNRUI offers OEM/ODM customization and can handle large-scale international projects.

SYNRUI provides comprehensive solutions, not just individual product sales.

You no longer need to separately find filter manufacturers, purification equipment manufacturers, or engineering companies; instead, you can obtain complete, verifiable, and executable air filtration system solutions through SYNRUI.

Product Advantages
 
01/

1. Self-produced Filter Media + Self-produced Filter Elements + Self-produced Equipment

Most products on the market only:

Buy filter elements → Assemble equipment

Buy fans → Pack

SYNRUI, however, possesses:

Filter media forming and folding lines

Automatic glue dispensing equipment

Metal sheet metal center

Complete equipment assembly line

More controllable quality.

02/

2. All products are tested individually, not randomly

Most products on the market are randomly inspected, while we:

Measure airflow/static pressure/noise of each FFU individually

Scan leaks on each HEPA filter individually

Test each piece of equipment during operation

Reduce quality risks.

03/

Higher aerodynamic efficiency design

Our air-end equipment uses an optimized airflow structure, which significantly reduces pressure loss and eddies, resulting in more uniform airflow in cleanrooms.

04/

Lighter and more durable structural design

Through structural optimization and material control, some products are 10-25% lighter than the industry average, while maintaining higher strength.

FAQ

Q: 1. How to select filters according to cleanroom class?

A: ISO3–ISO5: ULPA/HEPA (H14/U15/U16)
ISO6–ISO8: Medium + HEPA (H13)
We can select filters free of charge based on airflow, differential pressure, and equipment structure.

Q: 2. How often should the filters be replaced?

A: Typically 1–3 years, depending on dust concentration, pre-filter level, and usage hours.

Q: 3. How do you ensure the filters are leak-free?

A: We use EN1822/ISO29463 for unit-by-unit leak testing, not random sampling.

Q: 4. Can you provide complete cleanroom solutions?

A: Yes, SYNRUI can provide equipment + filter + airflow/velocity configuration solutions.

Q: 5. Do you support OEM/ODM?

A: Fully supported. We can provide drawings, labels, appearance, and size customization.

Q: 6. Why do your filters have a longer lifespan compared to others on the market?

A: Due to the use of high-capacity filter media, uniform pleating technology, and a lower resistance design.

Q: 7. How do you guarantee delivery time?

A: We have a safety stock system for raw materials and sufficient stock of standard products, enabling fast delivery.

Q: 8. Can you provide CE or third-party reports?

A: Yes, CE, ISO9001/14001/45001 certifications are all available, and CNAS third-party testing can also be provided.

Q: 9. Does the air-end equipment require commissioning?

A: Some equipment, such as FFUs, air showers, and HEPA boxes, require commissioning. We provide remote or on-site guidance.

Q: 10. Can different types of filters be mixed and matched?

A: A proper combination based on system pressure differential and airflow curves is required. We can provide professional solutions.
