IMS — BIG BANG FILTER BASKET 702TFH21.5BB
The IMS Big Bang is the latest innovation from IMS – fewer and smaller holes with a slightly smaller hole pattern and basket holes do not go to the edge like IMS baskets. The FH in the code means flat base. BB stands for big bang hole-boring pattern. Most IMS baskets have 715 holes and 1.75mm holes – the BB has 585 holes and 1.50mm holes. The basket’s hole pattern is unique due to the hole spacing – which gets smaller as you get closer to the center. This Big Bang pattern enables more flow through the center to offset side channeling.
