Product Description

82 Type Sintered Sight Glass – Inline Stainless-Steel Filter View Window

In pharmaceutical, food & beverage and fine-chemical processes, operators demand uninterrupted visual monitoring of clear, particle-free media while maintaining strict hygienic standards. Conventional sight glasses can trap residues between the glass and gasket, obscure vision with particulates, and require frequent shutdowns for cleaning—driving up downtime and contamination risk.
 
Particle Fouling & Obstructed View
Fine particulates or crystalline solids accumulate under standard sight-glass seals, rapidly clouding the viewport and forcing unscheduled line stops.
Lumistar's Solution:The 82 Type integrates a sintered 316L stainless-steel filter plate (2–10 μm) directly behind the glass, isolating solids while preserving crystal-clear visibility.
 
Lengthy CIP/SIP Downtime
Manual disassembly for cleaning or gasket replacement interrupts production, increasing labor costs and risking microbial ingress.
Lumistar's Solution:Tool-free Tri-Clamp, BSP or NPT screw-type connections enable on-line removal under pressure. Fully CIP/SIP capable up to 135 °C and 1.6 bar, the 82 Type restores hygiene without vessel shutdown.
 
Seal Leakage & Maintenance
Repeated assembly cycles or abrasive media wear O-rings, leading to leaks and batch rejections.
Lumistar's Solution:Redundant EPDM/PTFE dual-seal system and polished Ra≤0.8 μm surface finish ensure vacuum- and pressure-tight performance, minimizing maintenance and maximizing uptime.
 
Optimize your inline viewing and filtration with Lumistar's 82 Type Sintered Sight Glass—engineered for the highest productivity, safety and process integrity.
