HWZY - Medium and Low Pressure High Air Volume Industrial Fan

A: Yes, we support it. Our company has its own selection software and pneumatic laboratory. For special working conditions (such as special air volume and pressure, high temperature, corrosive gases, explosion-proof requirements, and limited installation space), we can customize the fan material (carbon steel/stainless steel/fiberglass), air volume and pressure parameters to meet individual needs.

A: Fans and dust collectors are industrial equipment. Piping layout and foundation fixation directly affect operating efficiency and stability. We recommend installation by a professional team. Our company provides nationwide on-site installation and commissioning services, along with installation manuals and video tutorials for customers to refer to when arranging their own construction.

A: 1 year warranty, with an 18-month warranty on core components (motor, impeller); the entire dust collector is guaranteed for 1 year (excluding consumable parts). For non-human-caused malfunctions within the warranty period, we promise a 2-hour response time, 24-hour on-site service within the province, and 48-hour on-site service outside the province, with free repair or replacement of parts.

A: Yes. The dust emission concentration of our dust collectors is ≤10mg/m³, which complies with the "Integrated Emission Standard of Air Pollutants" (GB16297-1996) and various local sub-industry standards. We can provide authoritative third-party testing reports to help customers pass environmental protection acceptance.

A: Yes. Our company offers a range of products with CE and ATEX certifications, and we also have a dedicated overseas department to handle inquiries and issues for most countries and regions. For overseas business inquiries, please contact: Eva: 18668917878 (same as WeChat), email: manager@tmsdusting.com.

A: The delivery time for standard model fans is 7-10 working days, and the delivery time for dust collectors is 10-15 working days; the delivery time for non-standard customized products depends on the design complexity and production schedule, and is generally 20-30 working days.

A: ① Fan: Regularly check the dust accumulation on the impeller (it is recommended to clean it once a month), the temperature and lubrication status of the motor bearings (add special grease every 3 months), and the belt tension (if applicable); ② Dust collector: Clean the dust hopper daily, regularly check the filter cartridge for blockage (clean or replace if the pressure difference exceeds 1500Pa), and check whether the pulse valve is blowing normally.

A: The replacement cycle for wear parts depends on the dust concentration and humidity of the operating conditions: under normal operating conditions, the filter cartridge replacement cycle is 3-6 months; under high dust concentration conditions, it needs to be shortened to 1-3 months. Customers can replace wear parts themselves; we provide detailed replacement tutorial videos and can also supply original parts.

A: ① Disconnect the power and close the inlet and outlet valves of the equipment to prevent foreign objects from entering; ② Clean the residual dust from the fan impeller, dust collector filter material, and ash hopper to prevent moisture and clumping; ③ Add grease to the fan motor bearings and apply anti-rust oil to exposed metal parts; ④ Keep the equipment room well-ventilated and dry to prevent electrical components from getting damp and damaged.

A: Our products are widely used in industries such as machining (laser cutting/welding/cleaning), building materials and cement, chemicals, food processing, non-ferrous metal smelting, furniture manufacturing, and explosion-proof dust ventilation and dust removal.

A: Yes. Our company has developed specialized wet dust collection equipment for high-humidity, sticky dust.

A:
ATEX is the EU's safety certification system for equipment used in explosive atmospheres. It is widely used globally and has stringent standards, with core directives including 2014/34/EU (Equipment Directive). Our ATEX explosion-proof fans are certified by the authoritative TUV organization and meet the requirements for Class II explosive atmospheres (factory scenarios), covering Zone 1/2 (gas explosion environments) and Zone 21/22 (dust explosion environments). We can provide complete explosion-proof certification certificates and declarations of conformity.

A: The selection of the appropriate explosion-proof rating requires matching three core parameters:
① Explosion-proof zone: Zone 1/21 requires "intrinsically safe/flameproof type," while Zone 2/22 can use "increased safety type";
② Gas/dust group: Match the corresponding group (e.g., IIA, IIB, IIC) based on the flammable and explosive medium (such as methane, aluminum powder, etc.) on site;
③ Temperature group: Select T1-T6 based on the ignition temperature of the medium (T6 has a maximum surface temperature ≤85℃, suitable for the most stringent scenarios). Our technical team can accurately match the explosion-proof rating based on the operating parameters.

A: Yes. For corrosive media (such as acidic gases in the chemical industry), we can customize fan impellers and housings made of 304/316L stainless steel; for high-temperature conditions (≤250℃), we can configure high-temperature resistant motors and heat insulation structures while maintaining explosion-proof performance. Please note: Detailed parameters such as media composition, temperature, and concentration must be provided before customization.

A: Explosion-proof fan installation must strictly adhere to explosion-proof specifications. Key requirements include: ① The equipment must be reliably grounded (grounding resistance ≤ 4Ω) to prevent static electricity buildup; ② Explosion-proof flexible conduits must be installed at the inlet and outlet to avoid sparks from rigid connections; ③ Electrical wiring must use explosion-proof sealed connectors, and exposed cables are strictly prohibited. It is recommended that the installation be carried out by a team with explosion-proof construction qualifications. Our company can provide installation technical instructions and on-site guidance.

A: Maintenance must adhere to the principle of "no damage to explosion-proof performance": ① Unauthorized modification of the fan structure or replacement of non-explosion-proof parts is strictly prohibited; ② Regularly check the integrity of the explosion-proof surfaces (no scratches, no rust) and apply special anti-rust grease; ③ Motor bearing lubrication must use explosion-proof certified grease. Replacement parts must use our original explosion-proof components. After replacement, please contact our technicians for explosion-proof performance verification.

A: Yes, they can be used together. For the renovation/energy-saving replacement of existing old dust collection equipment, our company provides explosion-proof fan solutions that meet explosion-proof requirements, and can also provide matching fan services for other explosion-proof dust collection manufacturers. We ensure that the entire set of equipment meets explosion-proof requirements and operates safely in explosive environments.
