Model IS
Double Deflection Grilles with Pole Operator
Pole operated industrial supply grilles / registers shall be model IS by Anemostat. Provide IS grilles for surface mounting and sizes as scheduled. Outer frame shall include countersunk screw holes for mounting. Grilles shall be designed to handle air velocities up to 3,000 fpm duct velocities and hold air pattern directional settings up to 45 degrees.  Front vertical blades shall be individually adjustable, and tensioned at each end with .090" diameter stainless steel music wire to hold deflection setting and prevent rattling.   Grille blades shall be 1-1/2" long, with a heavy, barrel tipped end to resist abuse. Tapered blades are not acceptable.  Blades shall be spaced at 1-1/2" to minimize pressure drop and sound levels, and minimize clogging and trapping contaminants. Front blades shall extend outward from the mounting frame for increased deflection performance, and to minimize collar depth into the supply ductwork. Rear blades shall be horizontal, and gang operated from a front lever to allow directional adjustment from the floor using a pole. The grilles / registers shall be painted with a baked-on arctic white finish.

Provide other accessories as scheduled which may include:  opposed blade volume control damper.

Model IS
Double Deflection Grilles with Sash Chain Operator
Chain operated industrial supply grilles / registers shall be model IS by Anemostat.   Provide IS grilles for surface mounting and sizes as scheduled.  Outer frame shall include countersunk screw holes for mounting.  Grilles shall be designed to handle air velocities up to 3,000 fpm duct velocities and hold air pattern directional settings up to 45 degrees.  Front vertical blades shall be individually adjustable, and tensioned at each end with .090" diameter stainless steel music wire to hold deflection setting and prevent rattling.   Grille blades shall be 1-1/2" long, with a heavy, barrel tipped end to resist abuse. Tapered blades are not acceptable.  Blades shall be spaced at 1-1/2" to minimize pressure drop and sound levels, and minimize clogging and trapping contaminants.   Front blades shall extend outward from the mounting frame for increased deflection performance, and to minimize collar depth into the supply ductwork.  Rear blades shall be horizontal, and gang operated by a chain / pulley arrangement to allow directional adjustment from the floor by pulling on the chain.  Chain length required shall be verified before installation.   The grilles / registers shall be painted with a baked-on arctic white finish.

Provide other accessories as scheduled which may include:  opposed blade volume control damper.

Model XW
Double Deflection Grilles
Double Deflection Grilles
Extruded aluminum industrial supply grilles / registers shall be model XW by Anemostat.   Provide XW grilles for surface mounting and sizes as scheduled.  Outer frame shall include countersunk screw holes for mounting.  Grilles shall be designed to handle air velocities up to 3,000 fpm duct velocities and hold air pattern directional settings up to 45 degrees.  Blades shall be tensioned at each end with .090" diameter stainless steel music wire to hold deflection setting and prevent rattling.  Grille blades shall be 1-1/2" long, with a heavy, barrel tipped end to resist abuse, and shall be individually adjustable.  Tapered blades are not acceptable.  Blades shall be spaced at 1-1/2" to minimize pressure drop and sound levels, and minimize clogging and trapping contaminants.   Front blades shall extend outward from the mounting frame for increased deflection performance, and to minimize collar depth into the supply ductwork.  Front and rear blades shall be perpendicular to each other, and the front blades shall be horizontal or vertical as scheduled.  The grilles / registers shall be painted with a baked-on arctic white finish.

Provide other accessories as scheduled which may include:  opposed blade volume control damper.
