1.1. Product design: The DHC-Hepa is a modular vertical cartridge dust collector combining primary cartridge filtration with downstream HEPA final filtration for industrial dry dust applications.

1.2. Cartridge installation: The primary filter cartridges are vertically installed with side access and secured by a clamp and pressure-rod structure, allowing convenient replacement without requiring top-access maintenance.

1.3. Two-stage filtration: The primary filter cartridges capture the main dust load and are automatically pulse-cleaned, while the downstream HEPA filter provides high-efficiency final particulate filtration.

1.4. Filter cartridge sizes: Standard cartridge diameter is approximately Ø324 mm, with common lengths of 1000 mm, 1200 mm and 1500 mm. Cartridge quantity and length can be selected according to airflow and filtration requirements.

1.5. Pulse-jet cleaning: The primary filter cartridges are automatically cleaned by compressed-air pulses to remove accumulated dust from the filter surface during operation.

1.6. Modular construction: Multiple filtration modules can be combined according to the required airflow and filtration capacity, providing flexibility for different industrial dust collection applications.

1.7. Vertical cartridge arrangement: Vertical filter cartridges help dust released during pulse cleaning fall toward the hopper and reduce dust accumulation on the upper surfaces of the filter elements.

1.8. HEPA final filtration: H13-H14 HEPA filters can be configured downstream of the primary cartridge filtration stage when enhanced control of fine particulate emissions is required.

1.9. Engineering support: Equipment dimensions, cartridge quantity and HEPA module configuration can be selected according to confirmed airflow, dust characteristics and available installation space.

1.10. International transportation: The modular structure is designed with overseas transportation and installation requirements in mind, helping simplify containerized shipping and on-site assembly.
