STEP SCREEN
Step screens are a regular feature on treatment plants throughout
New Zealand. We have chosen the Sam McCoy step screen
because it uses:
- thicker steel to handle tough operating conditions
- deeper and higher steps, so that larger screenings are removed and don't fall back into the channel requiring manual removal
- main bearings are above the waterline, requiring less maintenance and lasting longer
The Sam McCoy step screen is an alternative to currently available systems with a deserved excellent reputation for reliability and ability to handle tough operating conditions.
Sam McCoy screens originate from a European design originally built under license for many years at Sam McCoy's factory in Malaysia. Sam McCoy utilizes high precision German manufacturing machinery and each of their screens is supplied with full quality control certificates for materials, fabrication and testing prior to dispatch. Fabrication in Malaysia has the added advantage of short delivery times to New Zealand.

Simplicity of Function
Emphasis has been placed on reliable performance and ease of maintenance. All FSS screens are robust units made in either stainless steel 304 or 316.
The FSS Screen bars are teeth formed (termed lamellas) with half the lamellas mounted to a fixed frame and the other half to a moveable frame. These evenly spaced stepped lamellas trap solids and fine particles but allow liquid to pass through.
The solids build up on the lamellas which rotate lifting the mat step by step up the screen to be discharged at the top. This lifting action, coupled with the retention time on the screen, help in the dewatered screenings process.
The screening lamellas are anchored in place along the whole length of the unit ensuring rigidity and accurate spacing. The FSS screen's unique fixing arrangement allows for easy exchange of individual blades should the need arise.
Standard slot widths for the screen are 3mm or 6mm with corresponding standard screen sizes. Other dimensions are tailored to fit the requirements of the plant.
