Non-Ionising JetStream™ Air Knife System

JetStream is Meech's air knife system that delivers a uniform curtain of high-velocity air across the full width of a product or web. It is available in two versions: ionising JetStream — combines the air curtain with built-in ionization to simultaneously blow off particles and neutralize static charge, and non-ionising JetStream — delivers air only, for applications where static is not the primary concern. JetStream is used for surface cleaning of 3D products (removing particles, moisture, or debris), cooling hot products after processing, and drying surfaces after washing. The air knife design uses Coandă effect aerodynamics to amplify the compressed air supply, reducing air consumption by up to 90% compared to open nozzles.

Surface cleaners and ionizers are complementary — each solves a different part of the contamination problem. Ionization neutralizes the electrostatic charge that causes particles to stick to surfaces. Without ionization, cleaning systems have to fight against the attractive force of static — particles are pulled back to the surface immediately after removal. With ionization, particles are loosened and can be removed more easily and permanently. The optimal sequence: 1) Ionize the surface to release particle adhesion. 2) Clean using air knives, web cleaners, or vacuum to physically remove the particles. 3) Ionize again after cleaning to prevent re-contamination from ambient dust.

IonRinse is Meech's waterless container rinsing system that cleans the inside of bottles, jars, cans, and other containers using ionized air. The system inverts the container, fires a burst of ionized compressed air inside, and extracts the displaced particles through vacuum. This eliminates the need for water rinsing, which requires drying time, generates wastewater, and can leave residual moisture. IonRinse is widely used in food and beverage, pharmaceutical, and cosmetics packaging lines. It is particularly valuable for PET bottles and plastic containers that hold electrostatic charge — the ionization neutralizes the charge so particles release, rather than being held in place by static attraction.
