Vacuum Conveyor
CYprocess vacuum conveyors — also called vacuum feeders or vacuum loaders — transfer powders, granules, dust and small parts through closed pipelines. The enclosed path makes handling safe, hygienic and dust-free.

Overview
About Vacuum Conveyor
How this equipment works in powder handling lines and what to consider when selecting it.
Working principle
A vacuum source draws powder or granules through a closed pipeline to the filter receiver, where product separates from the conveying air and discharges through a flap, butterfly or rotary valve. The fully enclosed path keeps dust contained and the product protected.
Options and integration
Choose intermittent or continuous discharge. A level probe lets the unit start and stop by itself, and one station can serve several machines in rotation through diverter valves. Product-contact parts are SS304 or SS316L.

| CY-VC-250 | Φ250 × 900 | ≤500 | 4 | 0.45 | Intermittent | SS304 / SS316L |
| CY-VC-320 | Φ320 × 1100 | ≤1000 | 5.5 | 0.9 | Intermittent | SS304 / SS316L |
| CY-VC-430 | Φ430 × 1500 | ≤2000 | 7.5 | 1.35 | Intermittent | SS304 / SS316L |
| CY-VC-560 | Φ560 × 1800 | ≤3000 | 11 | 2.7 | Intermittent | SS304 / SS316L |
| CY-VC-250L | Φ800 × 1600 | ≤1200 | 5.5 | 0.9 | Continuous | SS304 / SS316L |
| CY-VC-320L | Φ900 × 2150 | ≤2500 | 7.5 | 1.8 | Continuous | SS304 / SS316L |
| CY-VC-430L | Φ1100 × 2600 | ≤4500 | 11 | 2.7 | Continuous | SS304 / SS316L |
| CY-VC-560L | Φ1400 × 3250 | ≤6000 | 15 | 5.4 | Continuous | SS304 / SS316L |
Capacities are indicative maxima for free-flowing powders over short conveying distances. Final sizing depends on bulk density, particle size, moisture and total conveying distance — confirm with our engineers before ordering. Custom sizes available. Model codes ending in L are the continuous-discharge versions.
General specifications
| Construction | SS304 / SS316L product contact |
|---|---|
| Filter options | UHMWPE / PTFE membrane / sintered titanium |
| Discharge | Intermittent or continuous; flap / butterfly / rotary valve |
| Cleaning | Compressed-air reverse pulse on filter |
| Air supply | Typically about 0.5 - 0.6 MPa clean dry air for pulse and valves |
| Control | Timer / PLC; optional level auto start-stop |
| Conveying line | Flexible hose or hard stainless steel pipe, sized per route and rate |
| Indicative capacity | Up to 3000 kg/h on intermittent models; up to 6000 kg/h on continuous-discharge (L) models. These are maxima for free-flowing powder on a short route. |
| Receiver size | From Φ180 × 700 mm to Φ1400 × 3250 mm across the listed models |
| Vacuum source power | 2.2 - 15 kW on the listed models |
| How the table should be read | Published kg/h falls as horizontal distance, vertical lift, bends, bulk density and moisture increase. Send the route before treating a model capacity as the plant rate. |
