Alfie, the simple to use separator from Alfa Laval! Turnkey, portable, small footprint, centrifugal disc stack separators that remove contaminating oil, grease and solid particles from water-based industrial fluids such as coolants and wash liquids. The effective separation down to small particle levels helps prevent tool wear, avoid disposal problems and lowers costs and fluid usage, resulting in a more sustainable and economical process.

Quick, continuous cleaning

  • Small, portable, effective centrifugal separation
  • Less downtime for service since you can connect Alfie to a bypass flow
  • Effective simultaneous separation of oil, grease and solid particles
  • Easy to install, use and service! Designed for operator convenience
  • Works with existing machinery with no retrofitting required

Industrial fluids play a key role in the service life and output quality of your machinery. Disc stack separation is proven to be one of the most effective ways to ensure these fluids are free of contaminating tramp/free oil and fine particles. Contaminants that can damage the machinery and make them less effective. 

Separation of industrial fluids also leads to longer fluid life, saving you money on purchasing and disposal. Reduced fluid use and disposal also contributes to sustainability goals and regulations. Using Alfa Laval's Alfie, you get an effective separator in a compact, turnkey unit that makes financial sense as well. Use the CoolCalc tool where you can calculate your return on investment with the Alfie separator and see how it stacks up against other separation solutions.

How it works 

Alfie systems separate phases quickly by using a centrifugal force that's 5,000 times stronger than the gravity used in traditional settling tanks.

The centrifugal force presses heavy particles outwards against the separator walls. The disc stack forces lighter particles to follow the heavier ones instead of the liquid, making separation more precise and efficient.

Choose the ideal system for your application

We offer systems for all types of fluids – whether you're a small workshop or a large factory.

Alfie 200

Alfie 200 is specially designed to remove contaminants from coolants in smaller systems, using the time-tested technique of centrifugal separation. Alfie 200 is designed for mounting on top of coolant tanks, and is fitted with a bellows that automatically adapts the inlet to the tank's fluid level


Alfie 500

Alfie 500 removes contaminating oil, grease and solid particles from coolants. The result is lower costs due to reduced fluid consumption, lower disposal costs and improvements in both product quality and working environment. Alfie 500 is a mobile system ideal for smaller applications, with special couplings that make it easy to connect and disconnect hoses quickly.

Cutting fluid separation

Keeping your cutting fluids free from solid and liquid contaminants prolongs tool and fluid lifetime, which means a lower total cost of ownership and less service downtime.

Wash liquid cleaning

When it comes to cleaning wash liquids, the replacement process can be costly thanks to disposal and downtime. With efficient separation, you can maximise productivity and efficiency for longer.


Save resources by cleaning cutting fluids

Cutting fluids are an essential part of many machining processes, and without the right care and attention they become contaminated and can cause problems. By effectively cleaning your cutting fluids, you can avoid these issues and reduce your overall operating costs. In this whitepaper we explain the pros and cons of the different cleaning methods, and help determine which is best for your business.
