A Butterfly Filter Bag is a type of filter bag often used in industrial applications like dust collection or liquid filtration systems. The term “butterfly” in this context can refer to either the shape of the bag, how it opens, or the clamping/fitting mechanism, depending on the manufacturer and use case.

Shape: The bag may have a wide, wing-like opening that resembles a butterfly’s wings, allowing for larger surface area and more efficient filtering.
Mechanism: Some filter bags use a butterfly-style clamp or valve for quick release or change-out.
Application: These are typically used in industries like cement, chemical processing, pharmaceuticals, or food production, where high-performance filtration is needed.
