CX-Series Centrifugal Blower (YBCB-CX)
Chill, cooling and drying air to hold film flatness and gauge at speed.
CLTextiles, Films & Footwear
Sector solution / Flexible films
Flexible-packaging film — BOPET, BOPP and laminates — is made and converted on fast webs, where cooling air and vacuum hold-down keep the film flat, cool and in register.

REQTypical duty requirements
Air & vacuum on a film / converting line
| Section | Duty | Recommended class |
|---|---|---|
| Chill / cooling air | Flatness & gauge control | CX centrifugal |
| Coating / lamination drying | Process hot air | Centrifugal blower |
| Web hold-down vacuum | Register & tension | Vacuum pump |
| Dust / fume extraction | Extraction air | CX centrifugal |
CTXWhat this sector runs
Film extrusion and orientation demand precise cooling; centrifugal air on the chill and cooling sections sets film flatness and gauge at high line speeds. On the converting side — printing, coating and laminating — vacuum holds the web against rollers and drums so it stays in register and tension-stable.
Drying air on coating and lamination lines, plus dust and fume extraction, add further centrifugal duties. Reading a film plant as web-cooling and drying air plus vacuum hold-down for converting is the recommended structure.

ENGEngineering notes
On a fast film line, gauge and flatness are set in the chill and cooling sections — uneven cooling produces uneven gauge that no downstream step can fix. Steady, balanced centrifugal air over the chill holds temperature uniform across the web at high line speed. A drifting blower prints its instability into the film as gauge bands; an in-house-balanced CX machine keeps airflow constant, which is why it is the recommended cooling class for film.
Through printing, coating and lamination the fast-moving web has to stay tight against rollers and drums to hold register and tension. Vacuum hold-down does that, and a drop shows immediately as misregister or wander. A YELV vacuum pump sized to the drum and roller demand keeps the web controlled at converting speed, so print and lamination land where they should — the cooling air and the hold-down vacuum together deciding whether a fast film runs clean.
On a fast film line any instability in cooling air or hold-down vacuum prints straight into the product as a gauge band or a register error, so steadiness is the real specification. A dynamically balanced blower holds cooling airflow uniform across the web, and a correctly sized vacuum pump keeps the web tight without fluctuation. Because these machines run continuously, efficiency matters too — sizing to the best operating point rather than derating an oversized machine keeps running cost down. For a film maker, choosing cooling and vacuum machinery for stability first, and energy second, is what keeps both quality and cost where they belong.

WHYWhy Yash Blowers
Fast film lines punish airflow instability with gauge and register defects, so steady blowers and vacuum matter. Yash Blowers dynamically balances its own impellers in Faridabad, since 1998, under ISO 9001:2015, and dispatches 300+ machines a day — keeping cooling air and web vacuum on a domestic chain.
