Basic Types: The S type nozzle holders fall into 3 classes: 1) The A - S series with integral fixing flange 2) The B - S series with loose fixing flange 3) The C - S series, similar to A - S but with no flange.
The T, U & V size nozzle holders are made for fixing by a loose flange, are generally supplied with an air vent screw and have edge filters fitted.
