HENITOM manufactures single-wall round and rectangular ducts plus insulated double-wall ventilation stacks—made to project dimensions for reliable supply and exhaust air.
One airflow requirement. Three construction paths.
Shape, insulation and steel arrangement are selected from the route, environment and project dimensions.
SWO-OCSWO-OC
Single-wall round system
A rigid, smooth-wall galvanized system for supply and exhaust air inside or outside compatible buildings.
SWP-OCSWP-OC
Single-wall rectangular system
Space-efficient rectangular ductwork for shafts, suspended ceilings and routes where height or width is constrained.
SWISWI
Double-wall insulated system
A free-standing insulated round stack with a non-combustible mineral-wool layer and four inner/outer jacket arrangements.
Put the right steel on each side of the insulation
OC indicates galvanized steel; LU indicates grade 1.4301 stainless steel. Final selection depends on the transported air and external exposure.

SWO-OC or SWP-OC
Efficient routes through homes and apartments
Round ducts are ideal where installation space permits. Rectangular ducts help when the route must fit a shallow ceiling or shaft.
- ✓Supply and exhaust air
- ✓Custom fittings
- ✓Project-sized route
Reliable circulation, precise routing and long service life
Correct air exchange
A properly selected supply and exhaust route supports a healthy indoor microclimate.
Flexible geometry
Round, rectangular and custom fittings solve simple routes and difficult installation constraints.
Rigid, tight assembly
Butt-welded fabrication and compatible connections support stable, reliable ductwork.
Project-specific production
Dimensions and non-standard elements can be manufactured against the ventilation design.
Every transition, branch and inspection point belongs to one route
Straight sections, elbows, tees, crosses, reducers, saddles, caps, inspection elements, clamps and custom transitions can be coordinated as one compatible system.
TECHNICAL COMPARISON
Choose shape and protection before choosing components
| System | Shape | Construction | Materiál | Typical role |
|---|---|---|---|---|
| SWO-OC | Round | Single-wall | Galvanized | General supply and exhaust routes |
| SWP-OC | Rectangular | Single-wall | Galvanized | Space-constrained ceilings and shafts |
| SWI | Round | Double-wall insulated | Galvanized / 1.4301 combinations | Independent indoor or outdoor stacks |
Frequently asked questions
Round or rectangular—which should I use?+
Round ducts generally offer efficient flow and simple modular assembly. Rectangular ducts are valuable where ceiling or shaft space is restricted.
When is an insulated SWI system needed?+
SWI is intended as an independent insulated ventilation stack, especially where the route needs thermal protection or passes through demanding exposure.
What do OC and LU mean?+
OC denotes galvanized steel. LU denotes grade 1.4301 stainless steel. SWI combines these materials independently for the inner and outer jackets.
Can HENITOM manufacture custom dimensions?+
Yes. Exact dimensions and non-standard elements can be prepared for a specific ventilation design after technical review.
Can the same system carry any air stream?+
No. Air composition, humidity, temperature, hygiene, fire and building requirements must be verified before material and construction are selected.
