Filterbank Caddy 250cfm – 450cfm (3 Filter options from: 5 Micron, 1 Micron, 0.1 Micron, Activated Carbon, Water Trap )

Description

High-Flow Modular 4-Stage Compressed Air Filtration System

This high-capacity modular filter bank is a robust, job-site-ready compressed air filtration solution designed for applications where airflow, flexibility, and air quality are equally critical. Built to support demanding industrial and hire environments, the system delivers up to 400 CFM while allowing users to configure filtration stages to suit each specific job.

Designed as part of a scalable POWER FULL / THE POWER FULL AIR approach, the unit provides professional-grade air treatment without the need for permanent infrastructure.

Four-Stage Filtration for Industrial Air Quality Control

The filter bank is configured as a true four-stage inline filtration system, delivering progressive removal of contaminants to protect downstream equipment and personnel.

Stage one is a cyclonic water separator with no internal element, using centrifugal force to remove bulk water and heavy condensate without restriction or consumable parts.

Stage two provides 1 micron particulate filtration, capturing fine solid contaminants and rust particles commonly found in compressed air systems.

Stage three is a 0.01 micron coalescing filter designed for high-efficiency oil aerosol removal, protecting sensitive equipment and processes from oil carryover.

Stage four is an activated carbon filter rated to 0.01 micron, removing oil vapours, odours, and trace hydrocarbons for applications requiring higher air purity.

Unused filter housings remain fully sealed and operational even when no element is installed, allowing the system to operate correctly with fewer stages when full filtration is not required.

Auxiliary Regulated Outlet for Low-Flow Demands

In addition to the main high-flow outlet, the unit features a secondary auxiliary outlet positioned after the full filtration train. This outlet feeds a regulated 1/4 inch port, ideal for smaller filtered-air demands such as breathing air support units, control air, or instrumentation. This allows a single filter bank to serve both high-volume and precision air requirements simultaneously.

Industrial Frame Design Built for Hire and Site Use

All filtration components are enclosed within a heavy-duty steel frame engineered to protect the filter housings from accidental mechanical damage while still allowing full access for servicing and element changes. The frame incorporates stackable geometry to reduce floor space, integrated lifting lugs for crane handling, and forklift slots for safe movement on site or in depots.

High-visibility reflective safety tape improves identification and safety in busy or low-light work areas, making the unit well suited to industrial, construction, and hire environments.

Connections, Capacity, and Flow

The filter bank is equipped with 1 1/2 inch inlet and outlet ports, fitted with medium-size MinSup A claw couplers for fast, secure connection. A full-bore outlet ball valve is included for isolation and control. The system is rated for airflow up to 400 CFM, making it suitable for high-demand applications without excessive pressure drop.

Optimised for Hire Fleet Flexibility

For hire companies, the unit is supplied as a complete filter bank with empty housings as standard. End users purchase only the filter elements required for their specific application, ensuring contaminated elements are not returned into hire circulation. This model reduces operating costs for hire companies while giving customers precise control over filtration performance.

Typical Applications

High-flow blasting and surface preparation
Industrial spray and coating systems
Breathing air pre-filtration and support systems
Multi-tool compressed air distribution
Temporary or mobile compressed air installations

This modular 4-stage filter bank delivers a practical balance of airflow, protection, and adaptability, making it a dependable solution for demanding industrial and hire-based compressed air applications
