Ultra-thick Even Flat Spray Nozzles
DDA
Large capacity pneumatic spray nozzles, featuring an ultra-thick, flat spray pattern, produce uniform droplets across the entire spray pattern area, with minimal variation in spray angle. Their uniform spray distribution makes them well-suited for use in a multi-nozzle arrangement. Additionally, their large free passage diameter makes them resistant to clogging.
