2007 Donaldson Torit Downflo SDF ADF-4 Dust Collector

High-Performance 2,800 CFM System | Ultra-Web® Technology

This 2007 Donaldson Torit ADF-4 is a robust, self-contained industrial cartridge dust collector designed for continuous-duty applications. Built with heavy-gauge steel and a high-output motor, this unit offers nearly double the airflow of standard 4-cartridge models. It is ideal for metalworking, welding fume extraction, grinding, and pharmaceutical powder applications.

Key Features & Performance Highlights

• Advanced Pulse-Jet Cleaning: Features an automatic compressed air pulse-cleaning system. This allows for continuous operation without downtime, as filters are cleaned in sequence while the fan is running.
• Photohelic® Gauge Control: Equipped with a Dwyer Photohelic differential pressure gauge. This system monitors filter loading and automatically triggers the cleaning cycle only when needed, significantly extending filter life and reducing compressed air consumption.
• Ultra-Web® Fine Fiber Technology: Designed to use Donaldson's proprietary Ultra-Web filters (MERV 15). These filters trap dust on the surface of the media rather than deep-loading, allowing for easier pulse-cleaning and cleaner air discharge.
• Chamber Silencer & Noise Reduction: Includes an integrated chamber silencer to reduce exhaust noise, making it suitable for indoor placement near workstations.
• Compact "Downflo" Footprint: The "Evolution" style downward airflow design utilizes gravity to help pull dust into the hopper, preventing re-entrainment and ensuring the lowest possible pressure drop.
• Industrial Waste Management: Features a 17-gallon waste hopper for easy dust disposal and a 6" straight inlet for simplified ductwork integration.
