Product Details
Each chamber door has 3 atomiser spray ports. A suitable atomiser
position will be determined during test spraying once the chamber
has been set up and calibrated to deliver 1ml in 4.5 +/- 0.2sec
with an air pressure of 12.5psi (pounds per square inch). Each
sprayer has been factory calibrated and should not need attention.
The atomisers are connected to the common air supply using the
silicon rubber tubing and 'T' connector. The glass cylinder is 12 inches (approx. 25cms) in diameter
and 24inches (approx. 50cms) in length with aluminium end plates
hinged to open. The atomisers are made of brass with adjustable
liquid and air jets. These are easier to calibrate and clean
than glass atomisers and are less liable to breakage.
The atomiser spray head can be easily disassembled for cleaning
but care should be taken when removing particles from the jet
plate. Do not clear obstructions from the jet using wire or any
implement that could distort or change the size of the hole.
Each jet plate is located by 2 screws and positioned with dowel
pins to ensure correct relocation. Obstructions can be removed
by immersing the atomiser in a solvent, and removing the chemical
pick-up tube and air inlet tube.
By removing the small screw at the coned end and the jet plate
all passages can be cleared with compressed air.
Satisfactory operation of the knock-down chamber requires the
use of an air compressor capable of delivering low pressures
up to 15psi with an output control valve to maintain a constant
12.5psi to the chamber atomisers. Apart from an external light
source the chamber is complete and ready for immediate use.
