Further Information:

Baldwin’s Direct Extractive Filter Probes feature an advanced design to extract sample gas and remove particulate while preventing condensation prior to the gas sample entering the heated sample line.

New Machine-Lathed Sure-Lock™ Filter Assembly
Baldwin’s new Sure-Lock filter assembly is precision machined and features a unique design to help ensure proper insertion into the assembly and to reduce the possibility of leaks. The filter head is inserted into a notch in the assembly to ensure proper alignment before locking it in place. The o-rings are tightened under compression, rather than being located on the sides of the filter head, to reduce the risk of leakage.

  • Available for Class 1 Division 2 and Class 1 Division 1 applications
  • Sure-lock filter reduces risk of leakage
  • Range of filter elements designed for various applications
  • Available with air blowback system

Options Available:

  • Schedule 40, Schedule 80, Hastelloy, and Durinert+ stinger probes
  • Sintered stainless steel, screen mesh, ceramic, glass fiber, and Hastelloy filter elements
  • Air blowback system with 115 VAC, 230 VAC, 12 VDC, or 24 VDC solenoid
  • Solenoid to close sample line when blowback is initiated
  • Gas cooling spool piece for high temperature gas sources
  • Various size flanges
  • Durinert™ or Teflon coated filter assembly option for corrosive gas streams
  • NEMA 4X stainless steel or fiberglass enclosure
