Our process for delivering high-capacity centrifugal exhaust fans, differential pressure air-filtration systems, and heavy-duty dust collectors.
We review your facility layout, existing ductwork, and particulate load to determine the required CFM, static pressure, and filtration class. A differential pressure baseline is established for the DPS-500 or HDC-2000.
Based on the assessment, we select the appropriate centrifugal fan model (CF-9000 or custom) and calculate the impeller diameter, motor horsepower, and housing configuration to match your continuous mass air flow needs.
We design the multi-stage filtration layout—pre-filter, HEPA, carbon stage—and specify duct diameters, branch takeoffs, and blast gates to minimize pressure drop and ensure even air distribution across all collection points.
Each unit is fabricated from heavy-gauge steel with powder-coated finish. We run a full-load test on the fan assembly, verify the differential pressure sensor calibration, and inspect the rotary airlock seal on dust collectors before shipping.
Our technicians install the system, connect ductwork, set the VFD parameters, and calibrate the automatic reverse-pulse cleaning cycle. We measure actual CFM and static pressure at key points to confirm performance matches the design.
We provide a walk-through of the digital display, filter change intervals, and emergency shutdown procedures. A maintenance log template and contact details for 24/7 support are included with the final documentation.
Straight answers about our centrifugal fans, filtration systems, and dust collectors — from sizing and installation to maintenance and compliance.
Our CF-9000 series delivers up to 45,000 CFM at 12 inches w.g. static pressure. For smaller installations we offer the CF-4000 (18,000 CFM) and CF-6000 (30,000 CFM). Each model uses a backward-inclined impeller for energy efficiency and lower noise.
The DPS-500 has an integrated sensor that measures pressure drop across the filter stages in real time. When the load reaches a user-set threshold, the system triggers automatic reverse-pulse cleaning — no manual intervention needed. The digital display shows current pressure drop and filter status.
Yes. The HDC-2000 is built with spark-resistant construction, including a non-sparking fan wheel and a grounded filter housing. The cyclone pre-separator removes 95% of coarse particles before they reach the main filter, reducing fire risk. It meets NFPA 652 guidelines for combustible dust.
Routine checks include bearing lubrication every 500 operating hours and inspection of the belt tension monthly. The hinged access door and removable bearing assembly make service quick. We recommend a full inspection annually — our team can provide a service contract.
We design modular systems that scale from 500 CFM to over 100,000 CFM. Our engineers work with your duct layout, particulate type, and space constraints to specify the right pre-filter, HEPA, and carbon stages. Contact us with your requirements for a custom proposal.
Standard HDC-2000 units ship within 4 weeks. Custom configurations with special motor voltages, explosion vents, or rotary airlocks typically take 6–8 weeks. We can expedite select models — call or email for current lead times.
Definitions and conditions that govern the interpretation of our product specifications and performance claims.
Continuous mass air flow refers to the sustained volumetric movement of air under a constant static pressure load, measured in CFM (cubic feet per minute) at a given fan speed. Our centrifugal exhaust fans are designed to maintain this flow for 24/7 operation without performance degradation, provided the system is installed within the specified duct resistance and ambient temperature range of -10°C to 50°C.
Fine particulate matter includes airborne particles with an aerodynamic diameter of 0.3 microns to 10 microns. Our differential pressure air-filtration systems are tested per ISO 16890 and ASHRAE 52.2 standards. The DPS-500 achieves a MERV 15 rating, capturing 95% of particles in the 0.3–1.0 micron range under nominal airflow conditions. Actual capture efficiency may vary with particle composition, humidity, and filter loading.
A heavy-duty dust collector is built for continuous operation in industrial environments with high dust loads, abrasive materials, or combustible dust risks. The HDC-2000 uses a 20 HP motor, 12-gauge steel housing, and a spark-resistant construction. It is rated for 12,000 CFM at 10 inches w.g. static pressure. Duty cycle is defined as 16 hours per day, 7 days per week, with scheduled maintenance intervals every 500 operating hours.
Performance figures are based on laboratory tests conducted under controlled conditions (20°C, 50% RH, sea level). Field performance depends on duct layout, filter condition, ambient temperature, altitude, and power supply quality. We recommend a site assessment by our engineering team before final system sizing. All claims are subject to the installation and maintenance guidelines in the product manual.
Standard warranty covers defects in materials and workmanship for 24 months from the date of shipment. Warranty does not cover wear items such as filter cartridges, belts, bearings, or damage caused by improper installation, electrical surges, or operation outside the specified environmental limits. Extended warranty options are available at the time of purchase.
