Mounted within a tough impact and weather resistant PELI case the F4500 unit can be removed from the case and used as a stand-alone unit, where this makes testing more convenient. 

 

F4500 Safe-Air Testers are fitted with internal lithium rechargeable batteries and in addition also have a battery tray which accommodates 6 AA alkaline type batteries. In the event that the rechargeable batteries are not sufficiently recharged then you can continue to use the instrument with either the Alkaline AA batteries or a mains power supply. 

 

The unit features a colour touch screen, menu driven display, making air quality testing both easy and quick to complete, with a typical test taking about 10 minutes. The detection parameters of EN12021:2014 are met or exceeded during the automatically controlled test by the use of Draeger detector tubes to establish levels of carbon monoxide, carbon dioxide, and water. For oil the instrument can use either the Draeger Impactor or oil tube. 

 

The new Draeger Impactor has no glass or hazard components and can test for all known synthetic and mineral oils. An 

inbuilt electronic sensor measures oxygen content and the percentage concentration is displayed, whilst an electronic flowmeter allows airflows of up to 600 l/min to be verified. 

 

The unit is designed to test low-pressure airline breathing systems but can be used with the F3002 high-pressure regulator assembly to test HP cylinders. Factair’s quality accredited instrument workshop provides recalibration and servicing for the unit. In fact a testimony to the robustness and quality of Factair’s Safe-Air Testers is that units over 10 years old are still in daily use. 

 

At the end of each test results can be stored within the F4500’s memory (up to 20 tests can be stored) and then downloaded via the USB cable into PC compatible software which is available to download from Factair’s website. This software provides an easy way to retain and print test results.
