Type L-LR
The Type L / LR nozzle features stacked lamellae construction for exceptional strength and pressure resistance. Precision-engineered for slot widths as fine as 0.1 mm (+/- 0.05 mm), it’s equipped with a base plate for residual emptying down to the nozzle level. The LR variant includes a closed base plate to prevent media loss in compact contact areas under 65 mm diameter.
