Performance Features

01

Roof Natural Vent

Round roof vents with 350 mm diameters maintain uniform airflow of 3058 CFM (5195 m³/h) per unit vent.
Roof vents effectively prevent internal condensation build-up and release trapped moisture from the upper headspace.
Heavy-duty galvanized steel construction provides tight weatherproofing against rain, snow, and ambient dust intrusion.

02

Axial Aeration Fan

High-performance axial fans with 2900 RPM motors deliver air volume ranging from 4426 to 5965 m³/h.
Axial fan power specifications range between 0.73 HP and 1.47 HP for moderate bin aeration requirements.
Direct inline motor connection design maximizes aerodynamic efficiency while maintaining compact physical installation footprints.

03

Heavy-Duty Centrifugal Fan

Heavy galvanized steel centrifugal fans feature specialized airfoil impellers that deliver high airflow with extended motor operational lifespans.
Centrifugal fans operate at 2900 RPM with 7–30 HP motor power, supplying 7728 to 32,380 m³/h air volume.
High static pressure output penetrates deep grain mass beds to eliminate localized hot spots and moisture pockets.

04

Aeration Bin Floor

Aeration floor profiles include I-beam, Wind symbol, and Earth types with floor panel widths from 300 to 500 mm.
Floor perforations feature 2 mm hole diameters specifically designed for wheat and corn aeration without material leakage.
Fully engineered steel support legs ensure uniform floor load distribution capable of carrying heavy bulk grain weight.

Applications

FAQ

Why do steel silos require more robust ventilation compared to concrete silos?
Steel silos exhibit twice the thermal conductivity of concrete silos, making them vulnerable to external temperature swings, especially in summer, which creates severe condensation and grain heating.
What is the benefit of the 2 mm perforation diameter on GSS aeration floors?
The 2 mm perforation size is engineered specifically for grains like wheat and corn, ensuring even distribution of airflow while preventing grain kernels from leaking through or blocking floor vents.
How do centrifugal fans differ from axial fans in grain storage applications?
Axial fans (0.73–1.47 HP, up to 5965 m³/h) provide continuous inline aeration for moderate airflow needs, whereas heavy-duty centrifugal fans (7–30 HP, up to 32,380 m³/h) supply massive air volume and high pressure required for deep grain beds in large silos.
