How do you ensure product quality?
We implement strict quality control measures throughout the production process of our air filters and purifiers, from the procurement of raw materials to final product testing, all following international quality management system standards. Additionally, we conduct regular performance evaluations and continuous improvements on our air purification products.
In which industries and scenarios can your products be applied?
Our air filters and purifiers are widely used across various sectors, including healthcare, industrial production, public facilities, and residential environments, providing professional solutions to improve air quality in diverse settings.
How many product grades are there, and what are the differences between them?
Our air purification products are categorized into preliminary, medium, and high-efficiency levels. Preliminary air filters are used mainly to capture larger particles like dust; medium efficiency filters can remove smaller particles like bacteria; high-efficiency filters are capable of capturing very small particles, such as viruses.
Air Filter Application
- Healthcare and Biopharmaceutical Industry
Efficient filters ensure aseptic conditions in production. For instance, knife-edge filters and FFU units purify air in pharmaceutical cleanrooms.
- Automotive Painting and Coating Industry
Top-hung filter cotton and fiberglass mist filters ensure paint quality and workspace cleanliness by capturing paint mist.

Food and Beverage
Industry
Air quality is critical in food processing. Bag-type filters maintain environmental hygiene, preventing contamination.
How to Determine the Quality of Air Filters?
Check the Efficiency Rating
Quality air filters meet or exceed industry standards. Seek HEPA for homes, MERV for commercial settings, ensuring efficient filtration.
Material Quality
Examine the materials used in the air filter. High-quality filters are typically made from durable, fine mesh materials that can trap small particles effectively.
Structural Integrity
Good air filters should have a robust and intact structure that can withstand the air flow without collapsing or deforming over time.
Certification and Compliance
Verify that the air filter has the necessary certifications and complies with relevant environmental and safety standards.
API 610 ISO 13709 Pumps
Our API 610 / ISO 13709 pumps are purpose-built to deliver maximum reliability, safety, and efficiency across the world’s most demanding chemical, petrochemical, and refining operations. Designed in full compliance with API 610 and ISO 13709 standards, these pumps ensure long-term performance in high-temperature, high-pressure, and heavy-duty process environments. Whether you need a robust centrifugal pump, a precise process pump, or an advanced API 610 chemical process pump, our engineered product line provides the durability and performance required for continuous operation in mission-critical industrial settings.
Our offering covers the full spectrum of API categories, including the highly reliable API 610 OH2 pump, widely used for chemical services, refinery circulation, and general industrial transfer systems. These single-stage overhung pumps are optimized for stability, hydraulic efficiency, and resistance to aggressive media. For higher pressure or more severe operating conditions, the API 610 BB2 centrifugal pump provides superior mechanical strength with a between-bearings design, ensuring exceptional rotor stability, reduced vibration, and extended service life in continuous heavy-duty applications.
Each API 610 pump is engineered with advanced metallurgy options—high-grade stainless steel, duplex alloys, high-temperature materials, and corrosion-resistant configurations—to handle a wide range of industrial chemicals, hydrocarbons, solvents, and corrosive liquids. These pumps are designed specifically for long MTBF (Mean Time Between Failures), making them ideal for critical production units where unplanned downtime is unacceptable.
For facilities requiring specialized transfer operations, our chemical centrifugal pump and horizontal chemical pump configurations combine hydraulic efficiency with strong corrosion resistance, meeting strict chemical processing standards. These pumps ensure stable flow performance and reduced energy consumption even in challenging environments with fluctuating temperatures and pressures. The design focuses on optimized shaft alignment, improved seal chambers, and enhanced bearing protection to maximize operational reliability.
As industrial operations increasingly demand higher output and uninterrupted reliability, our industrial pump and heavy-duty centrifugal pump solutions deliver exceptional mechanical robustness, superior sealing capability, and resistance to extreme process conditions. These features make them ideal for refineries, fertilizer plants, petrochemical complexes, power generation, offshore platforms, and general industrial processing.
Our product line also includes API 610 / ISO 13709 centrifugal pumps, engineered with precision-machined components, advanced hydraulic profiles, and optimized impeller-volute geometry. The result is smoother flow, minimized vibration, reduced NPSHr, and increased system efficiency. Each unit is fully tested under stringent performance and quality control procedures to ensure compliance with global standards and customer-specific technical requirements.
As one of the trusted API 610 pump suppliers, we provide complete engineering support—from pump selection and materials consultation to installation, commissioning, and long-term maintenance strategies. Our engineering team works closely with customers to evaluate operating conditions including temperature, fluid composition, viscosity, vapor pressure, and corrosion factors—ensuring the selected ISO 13709 pump configuration delivers maximum reliability and operational longevity.
When your operation demands uncompromising performance, long service life, and guaranteed compliance with international pump standards, our API 610 / ISO 13709 pumps provide a fully engineered solution built for modern chemical processing, refinery operations, and industrial fluid transfer. Precision design, robust construction, and proven field reliability make these pumps the ideal choice for high-value process installations worldwide.
