Max flow @ 100% duty
120 CFM

Max flow @ 70% duty
84 CFM

120 CFM w/PLC and PC systems

REMINDER: PC controller not illustrated however, distributes pilot signals in same sequence as a PLC controller.

The descriptions detailed on page “Twin Tower w/MLT” schematic represents the sequencing of air flow as it relates to the actual drying process and transition – wet to dry – within all dryer systems including Programmable Logic (PLC) and Pneumatically Controlled (PC) systems.

Programmable Logic Control (PLC) Applications 
(120, 240 400, 600, 800 CFM Dryer Systems)

1. Identify dryer system by counting numbers of desiccant cartridges, e.g., 2, 4, 6

2. Locate service component identity, e.g., A, B, C, etc.

3. Under “Qty”, order appropriate number of kits specific to cartridge total

A technical exploded-view diagram showing the assembly components of a mechanical device, likely a compressor. Two identical vertical housings labeled A sit at the top, aligned above threaded components B, bases I, and valves C. Red lines labeled D track the path down to a horizontal valve plate assembly. Lettered pointers indicate various internal components (H, K, L, M). On the right side, a standalone black power adapter block is pictured with an integrated, coiled power cable.
