High Impact Spray Header
with Quick-Detachable Nozzles

INVVEA■Integrated spray header equipped with INVVEA
series nozzles producing semi-fine atomization with amean droplet diameter of 50 μm or more.*1■Provides the same performance as VVEA: high spray
impact and uniform distribution with thin flat spray pattern.
■Ideal for washing away particles with fine fog spray.
■Quick-detachable nozzle tip design helps to greatly reduce
maintenance time.
■Made of highly chemical-resistant plastic.
■Nozzle tips are color-coded by spray capacity for easy
identification.

[Spray pattern][Spray distribution]*1) Droplet diameter measured by laser Doppler method

Nozzle tip isquick-detachable!

APPLICATIONS■Cleaning: Liquid crystal glass substrate, PC boards■Etching

DRAWING The drawings below are just a few examples. Dimensions and pipe connection sizes differ depending on the nozzle
code, nozzle quantity, nozzle spacing, and other requirements. For details please ask for our inquiry drawing.
*2) The number of mounting screws required increases as the total length gets longer.
*3) The mounting screws should be placed between the nozzles to avoid interference.
*4) When the total length is more than 1,000 mm, two or more headers are combined into one INVVEA Header.

Total length: 1,000 mm or less (available from 150 mm in total length)
