Ansul Air Cylinder and Tubing Assembly 015733

The Ansul 015733 is a complete air cylinder and tubing assembly for use with ANSUL Automan mechanical release systems in ANSUL R-102 restaurant fire suppression systems. The compressed air cylinder provides the pneumatic force needed to activate the system upon manual or automatic trigger — when the ANSUL Automan detects a fusible link release or manual pull station activation, it releases the compressed air from the 015733 cylinder through the tubing assembly to actuate the agent cylinder valve and initiate suppression discharge.

The 015733 assembly is a complete replacement unit — the air cylinder and tubing are supplied together, eliminating the need to source these components separately and ensuring the tubing is properly matched to the cylinder connection geometry. The compressed air cylinder must maintain its charge throughout the system's service life to guarantee reliable Automan actuation on demand. An undercharged or defective air cylinder can prevent system activation in an actual fire event. The air cylinder tubing must be inspected for kinks, corrosion at fittings, and physical damage that could restrict the pneumatic actuation signal.

Per NFPA 17A and NFPA 96, the Automan actuation system including the 015733 air cylinder and tubing assembly must be inspected at every semi-annual service visit. Verify the air cylinder charge is within the rated range, all tubing connections are secure and leak-free, and the tubing is free of kinks or damage. Replace the 015733 assembly if the cylinder is undercharged or any tubing defect is found. Available through authorized ansul distributors. The ansul automan ii-c and compatible Automan configurations utilize this assembly as specified in the ansul system near me service documentation and ANSUL R-102 system manual.

Semi-Annual Inspection

At every semi-annual NFPA 17A and NFPA 96 inspection, verify the 015733 air cylinder charge is within the rated operating range. An undercharged cylinder must be replaced before the system is returned to service — a depleted air cylinder cannot provide adequate pneumatic force for reliable Automan actuation. Inspect all tubing connections for leaks using a leak detection solution, and visually inspect the tubing for kinks, abrasion damage, or corrosion at fittings. Document inspection findings in the fire suppression system inspection record.

Post-Discharge Replacement

After any ANSUL R-102 system discharge, the 015733 air cylinder will be depleted and must be replaced before re-arming the Automan. Install a new 015733 assembly, verify all tubing connections are secure and leak-free, and confirm the air cylinder charge is at the rated level before returning the system to armed service. Document the replacement in the fire suppression system inspection record.

Can the air cylinder be recharged instead of replaced?

The 015733 is a complete OEM assembly — consult the ANSUL R-102 system documentation regarding whether the air cylinder component can be recharged separately or whether full assembly replacement is required. For most Automan configurations, replacing the complete 015733 assembly is the recommended service approach to ensure both the cylinder charge and the tubing integrity are reset simultaneously. Authorized ansul distributors can advise on the correct service procedure for your specific Automan configuration.

Is the 015733 compatible with the ansul automan ii-c?

Verify compatibility with your specific Automan model using the ANSUL R-102 system documentation or by consulting authorized ansul distributors. The Automan product family includes multiple configurations — confirm the 015733 assembly is the correct replacement for your system before installation. The ansul system repair documentation provides model-specific assembly compatibility information.
