An example of the implementation of a technological task for an individual order | Custom filter box for salt spray protection: solution to problems associated with special operating conditions through R&D.
2026-05-27
Salt spray corrosion has always been a major concern for equipment maintenance in special service environments such as industrial corrosion protection and equipment ventilation in coastal areas. Our company recently completed the production of a customized stainless steel salt fog filter box for a coastal industrial project. This equipment is specially designed to work in high concentration salt spray environments. Thanks to space optimization, washable design and modular system, it significantly reduces subsequent maintenance costs for the customer and provides a reliable guarantee of long-term stable operation of the equipment.
Project Background: Solving Three Major Problems in High Concentration Salt Fog Environments
1. Severe salt spray corrosion: High concentrations of salt spray in the air are easily deposited on the internal surface of the equipment, causing corrosion and short circuits in metal components, which greatly shortens the life of the equipment;
2. Insufficient filtration area: Existing filtration solutions have limited space, making it impossible to create sufficient filtration area, resulting in low salt fog collection efficiency and frequent filter replacement;
3. High Maintenance Costs: Traditional disposable filters are expensive to replace and the disassembly process is complex, resulting in downtime for maintenance and affecting the smooth operation of the project.
In response to the customer's specific operating conditions and key challenges, our technical team went through multiple design and optimization phases to ultimately develop this stainless steel salt spray filter box. From the design and choice of filter material to ease of operation and maintenance - everything is adapted to the real needs of the customer.
Specially designed stainless steel salt spray filter boxes are designed for use in coastal environments with high levels of salt spray exposure and feature a washable design that reduces subsequent maintenance costs.
3. Stainless steel material + anti-corrosion treatment: suitable for harsh coastal environments
The entire filter body is made of 316 stainless steel with a matte finish, making it corrosion-resistant and rust-resistant. It can work stably for a long time under high humidity and strong salt spray conditions. The corners of the housing are rounded to reduce dead spots for salt fog to accumulate. The quick-release locking design allows the door to be easily opened for cleaning and maintenance without complicated tools, and can be used by one person.
Key features of custom design: a comprehensive breakthrough from space optimization to cost control
This custom salt spray filter box features a number of targeted optimizations to address customer concerns. Key features include:
1. Space optimization: maximizing filtration area in limited space
Given the installation space limitations at the client's site, the technical team redesigned the internal structure of the filter box using a "multi-layer + modular" layout. In confined spaces, a metal mesh filter is integrated andplate filter G4Double layer filtration. This design not only significantly increases the effective filtration area, providing double interception of salt fog and dust, but also avoids installation and modifications associated with excessive equipment size, perfectly adapting to the customer's operating conditions on site.
The salt fog filter box adopts a multi-layer design combining metal mesh and G4 plate filter, which provides dual filtration in limited space.
2. Washable + quick-release design: reduce initial maintenance costs
To solve the problem of high filter replacement costs for customers, the filter unit combines washable and quick-release design:
(1) Pre-filterMetal mesh filter: Made of stainless steel woven mesh, can be washed repeatedly and effectively traps large salt spray particles and impurities, eliminating the need for frequent replacement and greatly reducing consumables costs;
G4 Post Plate Filter: Features a modular design that allows the filter to be quickly disassembled for tool-less replacement (2), reducing maintenance downtime;
Built-in Salt Spray Collection Container: A removable salt spray collection container is installed at the bottom of the filter unit, which customers can disassemble and clean regularly to prevent salt mist from accumulating inside the container and corroding the equipment, which further extends the life of the equipment and filter media.
The pre-filter can be washed repeatedly with water, which effectively traps salt spray impurities and reduces the customer's costs for its subsequent replacement.
3. Stainless steel material + anti-corrosion treatment: suitable for harsh coastal environments
The entire filter body is made of 316 stainless steel with a matte finish, making it corrosion-resistant and rust-resistant. It can work stably for a long time under high humidity and strong salt spray conditions. The corners of the housing are rounded to reduce dead spots for salt fog to accumulate. The quick-release locking design allows the door to be easily opened for cleaning and maintenance without complicated tools, and can be used by one person.
The filter box has a quick-release latch, is made of corrosion-resistant stainless steel, is suitable for coastal environments with high salt spray and simplifies subsequent maintenance.
