Weltech the ultrasonic welding solution
Weltech Technology ensures 100 % pleat alignment with no use of glue. An ultrasonic welding of each pleat tip to the retainer band requires no adhesive, which makes it non-collapsible even at high vacuum pressure.
Weltech provides several benefits:
- No glue or adhesives that could react with your process dust
- Perfect pleat spacing - for better filter cleaning performance and more even airflow
- Strong! - it will never crack
- Slim design - with no bulky bands to get caught in the tube sheet during installing and removing the filter
- Maximum temperature resistance is obtained
- The method is FDA compliant and ensures nothing fall off into the hopper
- Suitable for high temperatures, acid, hydrolysis or alkali substance
The technology is applicable for cartridge diameters up to 190 mm - otherwise USW bands are always an option.
