You are comparing reverse and rotary rainwater grille cleaning machines, let me help you sort out their core differences

Simply putReverse fishing is suitable for intercepting large floating objects and environments with high sediment content, while rotary fishing is more suitable for scenarios with high requirements for fine filtration and automation. Below, I will provide you with specific comparisons in several aspects:

1、 Working principle

• ‌Reverse fishing styleThe toothed rake is fixed to the chain and can be used to scoop up floating objects from bottom to top, suitable for intercepting large debris and sediment.

• ‌rotaryThe rake teeth rotate with the chain, continuously salvaging suspended solids, suitable for fine filtration and continuous work.

2、 Applicable scenarios

• ‌Reverse fishing styleCommonly used in coarse/medium grille scenarios such as rainwater pump stations and sewage treatment plants, especially suitable for environments with high sediment content.

• ‌rotarySuitable for medium/fine grid scenarios such as sewage treatment plants and rainwater pump stations, with a high degree of automation.

3、 Structural characteristics

• ‌Reverse fishing styleSimple structure, no transmission components underwater, easy maintenance.

• ‌rotaryThe rake teeth are self-cleaning and have a small gap (1-50mm), suitable for fine filtration.

4、 Selection suggestions

• ‌Choose reverse fishing styleIf dealing with large floating debris or sediment, such as rainwater pumping stations or industrial wastewater.

• ‌Select rotary typeIf fine filtration or automation is required, such as wastewater treatment plants or food processing wastewater.
