DETAIL

Product Details

1. Product Introduction

Shenzhen Mingyang Purification Technology Co., Ltd. has been deeply engaged in the air filtration field for over twenty years, focusing on the research and production of special air filters suitable for harsh working conditions. The high-temperature efficient filter is our core customized product, specifically designed for air purification needs in high-temperature environments, serving as a terminal filtration device with high-temperature resistance, high stability, and high precision in air purification systems.

Mingyang high-temperature resistant high-efficiency filters break through the temperature limitations of conventional high-efficiency filters, divided into three temperature resistance series: ≤250℃, ≤350℃, and ≤500℃. They are produced in strict accordance with the national standard GB/T 14295-2019 'Air Filters' and the international standard ISO 14644, with filtration efficiencies covering high grades H13 (99.97%) and H14 (99.995%). They use high-temperature resistant glass fiber filter materials and high-temperature resistant sealing glue, paired with stainless steel frames and high-temperature resistant separators, allowing for long-term stable operation in complex conditions such as high temperature, high humidity, and high dust, without deformation, melting, or leakage risks. The products are widely used in drying equipment, high-temperature ovens, industrial kilns, waste gas treatment, and new energy battery production, perfectly solving the industry pain points where conventional high-efficiency filters cannot adapt to high-temperature environments. They also support custom non-standard sizes, temperature resistance levels, and sealing methods, fully meeting personalized filtration needs for different high-temperature conditions.

2. Core product features

  • 2.1 Ultra-wide temperature range, suitable for all high-temperature working conditions: Provides three temperature resistance levels of 250℃, 350℃, and 500℃, capable of stable operation in high-temperature environments for extended periods, breaking through the temperature resistance limit of conventional efficient filters of ≤80℃, suitable for various high-temperature air purification scenarios such as drying, kilns, and exhaust gas treatment.
  • 2.2 High-temperature resistant special filter material, filtration accuracy does not degrade: Imported high-temperature resistant glass fiber filter material is used, treated for high-temperature shaping, which is non-deformable and non-melting at high temperatures, maintaining a stable filtration efficiency for ≥0.3μm ultrafine dust particles, bacteria, and smoke at H13/H14 levels, with no decrease in efficiency during long-term operation.
  • 2.3 Fully high-temperature resistant structure, zero leakage risk: The outer frame is made of 304/316L stainless steel, which is high-temperature resistant, corrosion-resistant, and non-deformable; separators are made of high-temperature resistant ceramic fiber/metal plates; sealing glue is made of high-temperature silicone, ensuring that there are no high-temperature melting points in the entire structure, guaranteeing 100% airflow passes through the filter material without short-circuit leakage.
  • 2.4 Large air volume, low resistance, efficient and energy-saving: The filter material uses high-precision pleating technology to maximize the effective filtration area, maintaining low resistance operation (initial resistance ≤180Pa) even under high-temperature conditions, reducing fan load and energy consumption, suitable for the long-term stable operation of high-temperature air supply systems.
  • 2.5 Corrosion-resistant and aging-resistant, long service life: The stainless steel outer frame and high-temperature filter material have excellent corrosion and aging resistance, showing no rust or aging under harsh conditions of high temperature and humidity, acid and alkaline waste gas, extending the service life by 3-5 times compared to conventional efficient filters, significantly reducing operational and maintenance costs.

5. Frequently asked questions

5.1 How to choose between high-temperature efficient filters and ordinary efficient filters?

For environments with temperatures ≤80℃, use ordinary efficient filters, which are more cost-effective; for environments with temperatures >80℃, select high-temperature efficient filters rated at 250℃/350℃/500℃ based on actual temperatures to avoid filter material melting and frame deformation, ensuring filtration effectiveness and equipment safety.

5.2 What is the replacement cycle for the high-temperature efficient filter?

Replacement cycles should be determined based on the dust content and temperature of the working conditions: Regular high-temperature clean working conditions require replacement every 12-18 months; high dust high-temperature working conditions require replacement every 6-12 months; when the resistance reaches the final resistance (400-450Pa), immediate replacement is necessary regardless of usage duration to avoid affecting the operation of the high-temperature air supply system.

5.3 Can the high-temperature efficient filter be cleaned and reused?

It is strictly forbidden to wash and reuse. The structure of high-temperature filter materials is precise, and washing with water can lead to deformation and fiber shedding, significantly reducing filtration efficiency; high-temperature baking can damage the filter material structure, posing risks of air and dust leakage. This is a one-time efficient filtration device that should be replaced directly when it reaches the end of its service life.

5.4 How to choose the appropriate temperature resistance level based on the operating temperature?

1. Conventional high-temperature conditions (≤250℃, such as ordinary drying ovens, food drying lines): choose the ≤250℃ series for high cost performance; 2. Medium-high temperature conditions (250℃-350℃, such as new energy battery drying, catalytic combustion equipment): choose the ≤350℃ series; 3. Ultra-high temperature conditions (350℃-500℃, such as kilns, RTO waste incineration furnaces): choose the ≤500℃ series, Mingyang can customize products with higher temperature resistance levels.

5.5 What special requirements are there for the sealing structure of high-temperature efficient filters?

High-temperature efficient filters use high-temperature silicone seals, which must bond tightly with the filter material and outer frame without gaps; during installation, high-temperature sealing gaskets must be used to ensure that installation interfaces are leak-free, avoiding short-circuiting of high-temperature airflow and affecting cleanliness.
