High Temperature Axial Fan
GKF GKT Drying Fan
Rated for 130 C ambient and 98 percent humidity, in eleven diameters and four mounting types, for paint lines, tobacco, rubber, pharmaceutical and timber drying.
High Temperature Axial Fans for Drying and Hazardous Areas
Four ranges rated for 130 C, 98 percent humidity, and in the CBF case for Zone 1 and Zone 2.

High Temperature Axial Fan Products
Four related ranges built around one idea: in a drying kiln or a hazardous area, the fan fails at the motor. Every fan in this category uses an all-copper H class 180 C motor with modified polyester imide enamelled wire, an aluminium alloy shell, stainless steel and copper fasteners and Japanese high-temperature grease, because those are the parts that decide whether the fan survives the season.
High Temperature Axial Fan
High Temperature Axial Fan
GKW GWF Wood Drying Fan
A wall type kiln fan in all aluminium, eight diameters from 400 mm to 1000 mm, built for reversible duty at 130 C and 98 percent humidity.
High Temperature Axial Fan
CRF Diagonal Grain Drying Fan
A patented diagonal flow design that cuts 40 to 50 minutes off a 15 T drying run and drops the noise from over 110 dB to within 85 dB.
High Temperature Axial Fan
CBF Explosion-Proof Fan
ExdIIBT4 marked to GB3836.2 and IEC 60079 for Zone 1 and Zone 2 areas, in four mounting types and six diameters.
The Problem
What Buyers Are Actually Trying to Fix
The applied conditions across this category are a maximum ambient of 130 C and a maximum relative humidity of 98 percent, in acid-deficient or mildly alkaline steam environments without combustible gas. Ordinary axial fans are not built for any of that, which is why they become a consumable in kiln service. Where combustible gas is present, the CBF explosion-proof range with ExdIIBT4 marking is the only appropriate product.
Who this range is for
- Timber drying kiln operators and kiln builders
- Grain dryer manufacturers and agricultural processors
- Paint lines, tobacco processing, rubber and pharmaceutical production
- Refineries, chemical plants, laboratories and medical facilities needing certified ventilation
- OEMs integrating fans into drying equipment as a build item
Typical application scenarios
- Timber drying kilns running reversible cycles
- Grain dryers at 15 T and 30 T scale
- Painting, tobacco, rubber and pharmaceutical drying, warehouses and basements
- Zone 1 and Zone 2 hazardous areas in petroleum, chemical and medical facilities
Every figure on the product pages in this
range comes from our own specification. Where a number depends on the diameter or
the duty it is written as TBC and confirmed at quotation.
Core Advantages
Why This Range Is Built the Way It Is
1
H class 180 C all-copper motor
Designed by advanced thermodynamic analysis so electromagnetic loading falls while efficiency rises, resistant to ageing and burnout in high-temperature and high-humidity vapour.
2
Externally lubricated bearing structure
The motor uses an external structure injected with lubricating oil, which extends bearing life and avoids dismantling the motor for lubrication.
3
Four mounting types on the main ranges
Wall, pipeline, fixed and square, so the fan fits the opening you already have rather than the opening being rebuilt.
4
One HS code across the category
8414599099, which keeps a mixed shipment of kiln, grain and explosion-proof fans straightforward to declare.

Questions
Questions About High Temperature Axial Fans
GKF GKT for general drying across eleven diameters and four mounting types. GKW GWF for timber kilns, in full aluminium wall type. CRF for grain dryers, where the diagonal flow design gives higher pressure than an axial fan. CBF wherever combustible gas is present.
130 C maximum ambient and 98 percent maximum relative humidity, with dust and hard particles not exceeding 150 mg/m3 in the carried gas. A customised high-temperature build is available where a duty sits outside that.
Only the CBF range. The others are explicitly specified for environments without combustible gas. CBF carries ExdIIBT4 marking against GB3836.2 and IEC 60079 for Zone 1 and Zone 2, gas groups IIA and IIB, temperature group T4.
Single phase 220 V, and three phase 220 / 380 / 660 V, 230 / 400 / 690 V or 240 / 415 V, at 50 or 60 Hz. The motor is wound for your supply.
Yes. The angle is adjusted to the client requirement at the factory, and arc or right-angle blade profiles are both available with 4 to 8 blades depending on diameter and duty.
