LS - KS

Product catalog summary

Overview
BETA series LS - KS semi-absolute filters are designed for high filtration efficiency and low pressure drop, optimizing energy consumption in systems. These filters feature a deep pleated design with micro-fiber glass paper and corrugated aluminum spacers, secured with an elastomeric sealant. LS filters have an MDF wood frame, while KS filters use a galvanized steel frame.

Specifications

Available in two sizes: 149 mm and 292 mm, both offering double filtering surface for higher air flow at the same pressure drop.
High dust holding capacity and mechanical resistance.
Efficiency (MPPS): ≥ 95% for both LS and KS models.
EN 1822:2009 classification: E11 for both models.
Suggested final pressure drop: 600 Pa.
Maximum pressure drop: 1000 Pa.
Maximum operating temperature: 90°C for LS, 100°C for KS.
Maximum relative humidity: 90% for LS, 100% for KS.
CE marked, with ATEX version available on request.

Technical Features

Dimensions and nominal air flow rates vary across models, with initial pressure drops of 150 Pa for 149 mm filters and 200 Pa for 292 mm filters.
Models are available in stock, with specific dimensions and air flow rates detailed in the technical table.

Performance
The filters are designed to maintain performance across varying air flow rates, as indicated by typical pressure drop curves.

Catalog excerpts

BETA series semi-absolute filters for duct flows BETA seies LS - KS semi-absolute filters offer very high filtration efficiency and low pressure drop, hence they allow for limited energy consumption levels in the systems. These filters are deep pleated version, with micro-fiber glass paper fitted with corrugated aluminum spacers; filtering pack fixed to the frame through an elastomeric sealant. LS filters have an MDF wood frame, whereas KS filters have a galvanized steel frame. Two different sizes, 149 and 292 mm with double filtering surface are available, to work with the same pressure drop but with higher air flow. All the models have high dust holding capacity and offer considerable mechanical resistance. ✓ Product ready in Stock / *1 m3/s x 10-3 = 1 l/s Technical draft Typical curves
