Storage system ventilation duct KM series

for grainmetal

Overview
Kongskilde supplies lateral ducts and accessories designed for on-floor drying and aeration of grain and seeds. The KMG and KMP series (KMG 900; KMP 1600 and 2500) integrate with commercial duct networks to deliver controlled airflow across the storage floor.

Product details
Semicircular lateral ducts are available in multiple diameters and tapered lengths to match airflow requirements. Sections can be combined and linked with gates, slides, transitions and endplates to form a continuous system from the main channel to the storage floor. Configurations such as KMP 1600 followed by KMG 900 reduce airspeed for economical drying of small seeds and cereals.

Key benefits

• Customizable modular design: Combine different duct sizes and accessories to create layouts adapted to building geometry and drying strategy.
• Controlled airflow distribution: Tapered sections and semicircular profile enable even air spread and reduced air velocity where required.
• Galvanized corrugated construction: Made from galvanized sheet metal with corrugation to provide compression strength for grain depths up to 10 m.
• Low air entry resistance: KMG side louvers maintain airflow even under grain cover, minimizing entry resistance.
• Removable for flexible use: Sections are designed for straightforward installation and removal when the space is reconfigured.

Perforation and variant details

• KMP: fully perforated, Ø2 mm holes.
• KMP R: fully perforated, Ø1.5 mm holes.
• KMP P: fully perforated, Ø10 mm holes.
• KMP T: closed top, perforated along the sides only.
• KMG: closed top with side vent louvres.

Applications
Suitable for on-floor drying and aeration in commercial storage systems for cereals, oilseeds (e.g., rapeseed), small seeds and specialized variants for root crops such as potatoes and onions.
