Custom Fan Protection: Performance in Harsh Environments
Built-in protection to keep fans performing in extreme conditions.
When people think about industrial fan customization, they often consider material, swapping mild steel for stainless steel or using aluminium to reduce weight. While that’s important, true performance depends on far more than the base material. It’s about the coatings, the enclosures, the finishes, and the seals that protect the fan in the environment in which it operates.
A fan made of the right material can still fail if it’s unprotected from washdowns, corrosive vapours, or salt air. That’s why ACI focuses not just on construction, but on protection.
In this blog, building on our previous look at everyday fan features, we focus on environmental customizations that protect performance in the harshest conditions.

How ACI Engineers Custom Fan Solutions
Smart Fan Features that Add Value
Protective Coatings: Battling Corrosion and Chemical Exposure
In environments where chemicals, cleaning agents, or saline air are present, corrosion resistance is essential. ACI offers a range of performance coatings, including stainless steel, PTFE, epoxy, marine-grade C5M, and easy-clean powder finishes, to provide an extra layer of defence.
These coatings:
Extend fan life in washdown or chemical-processing environments
-
Reduce the risk of surface degradation or paint flaking
- Support hygiene and food safety with anti-stick or easy-clean options
Custom coating is often what ensures a fan remains operational and compliant in the long run, especially in environments with high humidity, salt spray, or aggressive cleaning.

Ingress Protection and Weatherproof Motor Solutions
Fans destined for outdoor or dusty installations often require motor protection against water, dust, and environmental exposure. Rather than enclosing the entire fan, ACI offers IP-rated motors (e.g., IP55, IP66) as part of the fan build to meet environmental and compliance demands.
These motors are selected based on your operating conditions, offering protection where it’s most needed, directly at the source of the drive and control.
IP-RATED MOTORS
Motors with IP55, IP66 or higher ratings resist dust, moisture and washdowns, ideal for exposed or demanding environments.
MOTOR COVERS & SHROUDS
Optional drip covers and shields protect motors from overhead moisture and debris, without enclosing the whole fan.
GLANDS & GASKETS
Sealed cable glands and gaskets help preserve motor integrity by preventing water or dust from entering connection points.
These features are not generic add-ons; they’re specifically selected to match the environmental risks associated with your application.

Functional Finishes: From Branding to Hygiene Compliance
Fans can be supplied in custom colours or surface finishes to suit OEM branding or to match colour-coded zones in food or pharma production.
ACI can finish fans in colours that:
• Match your machine or equipment for brand consistency
• Support visual safety systems (eg red = danger zones, blue = allergen areas)
• Comply with hygiene zone standards using smooth, non-porous finishes
We also offer:
• Anti-bacterial coatings for hygiene-critical environments
• Low-gloss finishes for glare-sensitive spaces
• Easy-clean paints for quick wipe-downs
These finishes are often specified for appearance, performance, cleanability, and audit compliance.
Seals, Gaskets, and Fasteners: Built for Integrity
Many fan manufacturers offer “custom builds,” but this often means choosing from a list of existing options rather than solving a problem from the ground up. At ACI, customization is an engineering collaboration, not just a configuration checklist.
Rather than asking what fan you want, we ask: what problem are we solving together?
Whether you’re working with space limitations, system retrofits, or strict performance standards, we’ll help engineer the right solution, and we do this whether you need 100 units or just one.
When Does a Custom Fan Make Sense?
Depending on the operating environment, ACI fans can be supplied with sealed bearings, stainless-steel fixings, or added gaskets to prevent ingress.
GASKETED JOINTS
STAINLESS STEEL FASTENERS
Seal out moisture and particles at casing joins and access points.
Resist corrosion in washdown, marine, or high-humidity conditions.
DRAIN PLUGS
FOOD SAFE ADHESIVES
Allow moisture to escape, protecting bearings and internal components.
Use certified adhesives or silicone for hygienic environments like food or pharma.
Every detail is considered to ensure your fan maintains pressure integrity and complies with its environment.
Engineering for the Environment: Performance Without Overengineering
At ACI, we don’t just offer these options, we help you select the ones that matter most. That means you don’t overpay for unnecessary specs, and you don’t under-protect your equipment.
Real-world examples:
THE CHALLENGE
A wind turbine manufacturer needed a fan for use inside the nacelle, an environment exposed to salt air, temperature fluctuations, and long maintenance intervals. Standard fan materials corroded prematurely in offshore installations.
THE SOLUTION
ACI provided a custom solution with a C5M marine-grade coating, an IP66-rated motor, and stainless fasteners, ensuring long-term protection against moisture, salt spray, and vibration.
THE CHALLENGE
A an industrial bakery, where fans were used to extract warm, humid air from processing zones containing airborne flour dust, a combustible hazard in many food production settings.
THE SOLUTION
ACI supplied units with heat-resistant coatings, IP-rated motors, and custom gaskets. We also supported the customer with fan options suitable for ATEX Zone 22, ensuring safe operation in a potentially explosive atmosphere.
Our engineers ask the right questions to understand your environment and recommend what’s needed for performance and peace of mind.
