Industrial and food factory cleaning & washdown systems
Maintaining hygiene is a vital process particularly in the food processing, beverage and pharmaceutical industries. High-quality, efficient cleaning and disinfection equipment helps businesses meet even the most stringent sanitising requirements.
Washdown is the essential process of maintaining hygiene by removing soils, reducing bacteria to safe levels, and eliminating harmful pathogens across equipment, environments, and high‑contact surfaces. It brings together the three core hygiene actions: cleaning, which removes dirt and organic matter; sanitising, which reduces bacteria to safe public‑health levels; and disinfecting, which destroys viruses, bacteria, and fungi when deeper pathogen control is required.
Our washdown product range supports all stages of this process, from robust foamers and high‑pressure applicators to entryway systems and CIP solutions, helping facilities achieve consistent, compliant hygiene standards across food production, industrial, and commercial environments.
Making the most of every drop of chemical
Lafferty equipment is engineered to help facilities get the maximum performance out of every drop of cleaning and sanitising chemical:
- Precise venturi dilution systems ensure chemicals are blended at accurate, repeatable ratios
- Rich, clinging foams expand solutions to increase coverage and extend contact time without waste
- Many systems explicitly reduce over‑application by providing visual confirmation of full surface coverage and by using metering tips that control exactly how much concentrate is drawn.
- Equipment is simple to use and can be placed strategically for easy access and wherever washdown needs to happen
Together, these features allow operators to achieve superior hygiene results while using chemicals efficiently and responsibly.
Solutions include:
Entryway Sanitising Systems
What they are:
Automated foam‑applicator systems that project sanitiser onto entryway floors to prevent cross‑contamination. These systems operate using UK mains water pressure (typically 1–4 bar) and create clinging foam via venturi dilution with compressed air for increased coverage and contact time.
Benefits:
- Automated, repeatable sanitising at set intervals
- Consistent dilution and coverage
- Adjustable foam wetness
- Ideal for moderate‑ to high‑traffic hygiene‑critical areas
Products
- Timed Entryway Foam Sanitiser (976500):
Designed for personnel doors (≈0.9 m width). Single Spreader™ nozzle with a 3' × 4' pattern. Timer‑programmable; available in 24 V. - Timed Entryway HV Foam Sanitiser (976560):
Designed for wide overhead doors (≈2.4–4.8 m). Uses dual HV Spreader™ nozzles for wide coverage. Optional alert strobe; available in 24 V.
Hand Hygiene Dispensers

For high‑pressure water lines (~27–69 bar). Atmospheric‑air entrainment produces strong foam throw (up to ~3.6 m).
Mains‑Pressure Foamers (≈1–8 bar supply)
What they are:
Wall‑mounted foamers that use standard or boosted mains water pressure plus compressed air to generate rich, clinging foam for medium‑to‑large surfaces.
Benefits:
- Reliable venturi dilution
- Adjustable foam wet/dry consistency
- Water and air gauges reduce setup time
- Durable stainless‑steel or polypropylene construction options
Products:
- LC Foamer (915105‑G):

High / Boosted‑Pressure Foamers (≈8–70 bar)
What they are:
Foamers designed for boosted water systems or pressure washers. Use venturi dilution + compressed air to produce large volumes of clinging foam with long throw distances.
Benefits:
- Rapid coverage for large areas
- Strong foam projection (up to ~4 m)
- Highly chemical‑resistant stainless components
- Ideal for industrial washdown
Products:
- HPSS Foamer (918115) / HPSS Foamer (No Hose) (918115‑NH):
