The advantages of Plastic Filter Housing over metal alternatives

Introduction: what are Plastic Filter Housings?

A Plastic Filter Housing is a pressure vessel in which filter elements, such as cartridges or bag filters, are placed to remove solids from liquids. They are designed to filter a variety of water types, including wastewater, well water, process water, drinking water, cooling water, site water, leachate water, gray water, surface water and even seawater. Thanks to their robust design, versatility and corrosion resistance, they are being used in an increasing number of industries as a full alternative to metal housings.

The housings are typically made of reinforced polypropylene, available in sizes from 5″ to 20″ and available in transparent and non-transparent versions. Each Plastic Filter Housing undergoes rigorous strength and quality testing and is manufactured from FDA-approved materials. This ensures both safety and durability.

When do you choose a Plastic Filter Housing?

Plastic filter housings are the smart choice in situations where weight, corrosion resistance, hygiene or cost efficiency are critical. They are often used in:

• outdoor installations, exposed to moisture and weather;
  
• filtration processes with aggressive fluids such as salt, chlorine or acids;
  
• industries with high demands for food safety and drinking water quality.
  

Benefits of Plastic Filter Housings

Lightweight & ease of installation

Plastic Filter Housings are up to 70% lighter than metal variants. This allows them to be installed by one person without lifting equipment. This makes them ideal for temporary or mobile installations.

• Reduced labor costs thanks to easy assembly.
  
• Safer and more ergonomic work for mechanics.
  
• Quickly deployable for temporary projects such as sprinkling or emergency supplies.
  

Corrosion resistance & longevity

Polypropylene and other plastics are impervious to rust and chemical attack.

• No rusting even in outdoor applications or when in contact with seawater.
  
• High resistance to aggressive liquids, including chlorinated water and acids.
  
• Less maintenance and longer life because expensive coatings or overhauls are not required.
  

Cost Benefits

In addition to the lower purchase price, Plastic Filter Housings are also economically attractive to use.

• Lower acquisition cost than stainless steel.
  
• Lower transportation costs due to low weight.
  
• Reduced risk of costly replacement or overhaul due to corrosion resistance.
  

Hygiene & Safety

Many Plastic Filter Housings are FDA and WRAS certified.

• Suitable for drinking water and food & beverage applications.
  
• No risk of metal ions or rust particles in water or product.
  
• Safe and reliable for critical processes.
  

Flexibility & Applications

Plastic Filter Housings are widely applicable and easily adapted to specific processes.

• Available in various sizes (5″-20″) and transparent or non-transparent versions.
  
• Different connection sizes and micronages possible.
  
• Compatible with different filter elements, such as cartridges or bag filters.
  

Common applications include:

• inlet water, process water and cooling water;
  
• injection water and ballast water;
  
• prefiltration in food and beverage production;
  
• agriculture and greenhouse construction;
  
• wastewater treatment plants and industrial processes.
  

Sustainability and future-proofing

Plastic Filter Housings fit well into the sustainability goals of modern businesses.

• Recyclable material contributing to circular economy.
  
• Less energy-intensive manufacturing process compared to metal.
  
• Lower carbon footprint in production and transportation.

Conclusion

Plastic Filter Housings are more than a light and inexpensive alternative: they are a durable, safe and efficient choice for companies looking for reliability and flexibility in their filtration processes. In many cases, they are even the smarter choice over metal housings.
