Technical Specifications of AF Model Filters

This document provides detailed specifications for a series of AF model filters, focusing on dimensions, filtration capabilities, and maximum recommended flow rates.

1. Model Identification and Dimensions

Models: AF4, AF6, AF8, AF10, AF12, AF14, AF16
Inlet Diameter (ΦB): Ranges from 4 inches (450 mm) to 16 inches (900 mm)
Filter Diameter (ΦD): Varies between 18 inches (720 mm) and 36 inches (1400 mm)
Height (H): From 28.3 inches (80 mm) to 55.1 inches (1400 mm)

2. Filtration Parameters

Two filtration mesh sizes are specified: 1200 micron and 2500 micron
Each model has a maximum recommended flow rate depending on the mesh size:

For 1200 micron mesh: Flow rates range from 100 m³/h (440 gpm) for AF4 up to 1200 m³/h (5283 gpm) for AF16
For 2500 micron mesh: Flow rates range from 5 m³/h (22 gpm) for smaller models up to 6.5 m³/h (28.6 gpm) for larger models (note: these values appear inconsistent and may require verification)

3. Key Observations and Recommendations

The maximum recommended flow rates increase with the size of the filter model, reflecting their capacity to handle larger volumes.
Dimensions and flow rates are critical for selecting the appropriate filter model based on system requirements.
Some flow rate values for the 2500 micron mesh appear unusually low compared to the 1200 micron mesh and may need clarification.

4. Summary Table Overview

The table summarizes the following parameters per model: inlet diameter (ΦB), filter diameter (ΦD), height (H), maximum recommended flow rates for two mesh sizes (1200 micron and 2500 micron), expressed in both cubic meters per hour (m³/h) and gallons per minute (gpm).

This data is essential for engineers and technicians to ensure proper filter selection and system design.

Series AF - Self-cleaning suction filters-1

DROP Filtration Systems Irrigation Equipment The filtration grade ranges from 1500 to 2000 microns. Their anti corrosive protection includes surface treatment using phosphoric acids followed by electrostatic polyesteric paint, while other available paint and material options are also available pending request. The product is supplied with multiple couplings and flanges options availability (DIN,ASA, etc) conforminng to all required international standars. The recomented operating pressure range is 2 to 3 bars (29 to 43,5 psi). SELF CLEANING SUCTION FILTER __ . AF series The AF series filters have applications in any pumping installations sue as rivers, lakes, wells, tanks etc. The AF series filters are used as primary filters installed before the pump inlet. An important advantage is that due to their self cleaning ability they minimize the pumps maintenance needs as well as increase its efficiency. The benefits of the AF series filters are: Protection of centrifugal pumps and turbine: The filters protect the blades and minimize the creation of suction cavities. Energy consevation: They decrease losses due to pump wear, minimize the required pump maintanance(as explained below), while the ongoing cleaning of the filtration surface decreases the pressure losses. Maintanance: They increase the time interval between the required scheduled maintanance of the pump Unaffected continous system operation:The periodic self cleaning function does not require system shutdown during cleaning operation. The AF series filters are constructed from stainless steel sheet which is supported on a metal frame painted using electrostatic polyester paint 120 micron thickness. A water jet spraying system is installed internally. supply line Stainless steel Water jets Heavy duty An AF series filter installation typically includes: 3. Inlet pressure pipe 5. Three-way valve regulator 6. Screen filter 7. Cleaning watersupply pipe The filter is cleaned by means of reverse washing. During the self cleaning the jet spraying system rotates and sprays with presssure the entire filtration surface..
