The new Ajax 8250H High Pressure Regulator now fits both 4500 PSI & 5500 PSI air cylinders.
Each
 Ajax Rescue Kit features an air hammer specially selected for its 
durability and dependability. Every Rescue Kit includes an Ajax Kwik 
Change Retainer. The Kwik Change Retainer was originally developed by 
Ajax to hold the cutting tool securely in place, yet allowing the 
technician to change tools in a matter of seconds during emergency 
procedures. The Kwik Change Retainer also allows the technician the use 
of Ajax Exclusive Non-turn chisel bits. These Non-turn bits can be 
indexed into different positions to allow one-hand operation of the 
hammer when necessary. The Ajax Kwik Change Retainer is the only 
retainer that lets you use both Turn type and Non-turn type chisel bits.
 The Ajax Rescue Tools high-pressure regulator has a universal design 
which allows the technician to use either 2216 psi or 4500 psi air tanks
 without having to change the regulator. This regulator is rated at an 
operating pressure up to 300 psi, which is well above the recommended 
operating pressure of most air tools. Normal body metals, such as, A, B 
and C posts, quarter panels and firewalls require only 90 psi. However, 
heavier metals, such as Nader pins, door hinges, etc., may require 
150-160 psi.  A safety blow-off valve prevents the technician from 
exceeding the maximum pressure capacity level. This regulator lets you 
operate the tool at the proper air pressure essential for the most 
efficient operation while allowing you to use extra air power when 
needed. This allows the rescue technician to adjust to a higher 
operating pressure when attempting to cut through heavier steel, and 
complete a successful rescue or extrication.
Features: 
- User Friendly Architecture - The side mounted knob makes it 
easier to adjust, with a more natural and safer hand/body position for 
adjusting delivery pressure.
- Advanced Design - Smaller and lighter than our previous models.
- Durable
 Construction - Most regulators have multiple impact points. The Ajax 
8250H regulator is designed with a single impact point configured to 
help protect elements critical to system integrity.
- Compact Layout - Gauges are built in and recessed into the body for protection.
- Outstanding
 Flow Performance - They provide better flow control across a full range
 of cylinder pressures, with exceptional sensitivity in delivery 
pressure control.
- SLAM Technology - Shock Limitation and 
Absorption Mechanism built into the adjusting knob helps protect vitals 
and reduces the chance of injury in the event of a cylinder accident.
