PRODUCT OVERVIEW
Two Greek words, Anemos Statikos, were selected and combined to form the word Anemostat, which literally means to
control wind. Since 1934, our products and components have reflected this name, and have stood for quality, durabili-
ty, and reliability.
Over seventy years ago, our founder F.J. Kurth, developed a design for diffusing air in ventilating and air conditioning sys-
tems from the scientific principle of aspiration. Since then, he and several gifted engineers have researched and devel-
oped a wide range of air distribution products that have been installed worldwide. Anemostat has long been a recog-
nized leader in the air distribution industry with our complete line of air products and HVAC control systems.
Anemostat has acquired the rights to further develop and distribute the S-Vent®
product line for security applications. This proprietary and highly unique product
line was developed to combat physical and performance problems associated
with HVAC grilles in areas where confined living quarters exist.
Some of these common problems include suicide, contraband storage and
weapons sources, obstructed ventilation and excessive corrosion. Fortunately
what has become a burdensome and expensive maintenance item can be virtu-
ally eliminated with the use of the S-Vent® line of products.
A unique “S” channel design with vertical mullions provides the throat of these
grilles a rigid depth, which extends from 1-7/16” to over 4” behind the face. This
provides a level of security unsurpassed in the industry.
In addition, the grille line is augmented with the only security diffuser that does not require a faceplate. Directional air-
flow in 1,2,3,4 way throw patterns without faceplate and the “dumping” that traditional security diffusers provide, is what
you’ll receive with this offering.
The Product Directory on the inside cover, provides a listing of each product with suggested applications. These include
installations in adult correctional facilities, psychiatric hospitals, juvenile detention centers and other areas of confine-
ment where extra product strength is required. Sample product specifications can be found on the last page of this
brochure.
Our engineering staff has the capability and willingness to take on unique and special applications to satisfy your securi-
ty needs, meeting or exceeding ASTM requirements. Put our sixty-five years of experience and long standing reputation
for quality and performance to work for you. We have a worldwide network of trained and qualified representatives to
assist with your job requirements.
Anemostat offers a unique approach and unlimited choices for meeting the safety and comfort requirements of your
building. We have the strategies and solutions for all of our special applications.

SV2 Extra Heavy Duty PREMIUM GRILLE PRODUCT DESCRIPTION
MAXIMUM SECURITY1/8" x 1/8" Openings
STANDARD FEATURES• FACE FLANGE: Beveled Edge - 12-gauge C.R.S.
• OPENINGS: with 1/8” x 1/8” Horizontal Louvers and VerticalMullions of 12-gauge C.R.S.
• AIR PASSAGEWAYS: Patented “S” style eliminates ‘looping’ ofmaterials around/or through louvers
• NECK: Rigid with 1-7/16” exposed face depth made of multiplepiece 12-gauge construction
• INSTALLS: Coupling nut with threaded rods attaches to rear offace flange and duct connector
• DUCT COLLAR: Mating 14 gauge galvanized mounting framewith nuts (integral face/duct connection)
FINISH • Multi-stage surface preparation and powder coat finish
(5-7 mil. thickness) beige or white, must specify .
• OPTIONAL: Custom powder coat colors.Rust inhibiting prime coat.Consult factory for other finishes.
OPTIONAL FEATURES• MATERIAL GAUGES: other material gauges available
• MATERIAL: stainless steel
• FACE MOUNTED: connections available
• PATENTED PLENUM BOX: for retrofit connection
• SLEEVE AND LOCKING ANGLES
• OPPOSED BLADE DAMPERS: Rear operated
• ANCHOR STUDS: Nelson type for precast/brick wall applications
• TAMPERPROOF SCREWS: Stainless steel screws (see insideback cover, page i) will be furnished based upon the product andtype of installation (see pages A-14 and A-15)
CONSTRUCTIONThe grille is made of 12-gauge steel (stainless steel if used in humidareas) with the outer perimeter stamped to raise the grill face5/16” from the wall or ceiling. The edge of the grill is manufacturedwith a beveled slope. The portion of the edge of the grille that willcontact the wall or ceiling upon installation is machined to a flatnessof ±0.003”. No open or unfinished edges exist. The horizontallouvers are attached to a uniweld frame and ‘locked in’ to preventmovement or removal. The vertical mullions are correspondingly‘locked in’ place creating a penetration proof neck and throat of 1-7/16” depth. Coupling nuts are attached to the back of the faceflange for use with threaded rods. A mating duct collar with nutsreceive the threaded rod and are tightened accordingly.
INSTALLATIONSV2 is installed into the wall (or ceiling) with the threaded rodsattached. A mating duct collar with nuts receives the rod and isthen tightened to insure a secure fit on both sides of the wall.Optional attachment mechanisms are available for both new andretrofit applications. Optional sleeve, locking angle and opposedblade dampers may be supplied, if required. See pages A-14 andA-15 for Installation Overview.

SIZING CHART
TEST STANDARD• ANSI / ASHRAE Standard 70• Isothermal air used during testing.
SOUND LEVELS• NC shown is the noise criteria curve that will not be exceeded at the
operating point. This is determined by assuming a 10dB (ref: 10-12 watts)room attenuation that is subtracted from the power levels in each of the2nd thru 7th octave bands.
• When an opposed blade damper is used, add nc adjustment as shown onpage E-5
PRESSURE• Pt represents Total Pressure, inches of water, measured in the supply
duct.• Static pressure may be calculated by subtracting the Velocity pressure
from the Total Pressure: Ps = Pt - Pv
RETURN USE• Adjust the above supply data by adding +1 NC and use Pt as listed.

TEST STANDARD• ANSI / ASHRAE Standard 70• Isothermal air used during testing.
SOUND LEVELS• NC shown is the noise criteria curve that will not be exceeded at the
operating point. This is determined by assuming a 10dB (ref: 10-12 watts)room attenuation that is subtracted from the power levels in each of the2nd thru 7th octave bands.
• When an opposed blade damper is used, add nc adjustment as shown onpage E-5
PRESSURE• Pt represents Total Pressure, inches of water, measured in the supply
duct.• Static pressure may be calculated by subtracting the Velocity pressure
from the Total Pressure: Ps = Pt - Pv
RETURN USE• Adjust the above supply data by adding +1 NC and use Pt as listed.

SV49 Heavy DutyPREMIUM GRILLE PRODUCT DESCRIPTION
MAXIMUM SECURITY3/8" Horizontal Openings
STANDARD FEATURES• FACE FLANGE: Beveled Edge - 16-gauge C.R.S.
• HORIZONTAL LOUVER: spaced at 3/8” at 50° for directionalairflow
• AIR PASSAGEWAYS: Patented “S” style virtually eliminates‘looping’ of materials around/or through louvers
• NECK: Rigid with 3-1/4” face depth made of uni-welded constructed louvers
• DUCT COLLAR: Mating 14 gauge galvanized mounting framewith nuts (integral face/duct connection)
FINISH • Multi-stage surface preparation and powder coat finish
(5-7 mil. thickness) beige or white, must specify .
• OPTIONAL: Custom powder coat colors.Rust inhibiting prime coat.Consult factory for other finishes.
OPTIONAL FEATURES• MATERIAL GAUGES: other material gauges available
• MATERIAL: stainless steel
• FACE MOUNTED: connections available
• SLEEVE AND LOCKING ANGLES
• OPPOSED BLADE DAMPERS: Rear operated
• ANCHOR STUDS: Nelson type for precast/brick wallapplications
• TAMPERPROOF SCREWS: See inside back cover, page i, andconsult factory for specific product applications
CONSTRUCTIONThe grille is made of 16-gauge steel (stainless steel if used inhumid areas) with the outer perimeter stamped to raise thegrill face 7/16” from the wall or ceiling. The edge of the grillis manufactured with a beveled slope. The portion of the edgeof the grille that will contact the wall or ceiling upon installationis machined to a flatness of ±0.003”. No open or unfinishededges exist. The horizontal louvers correspondingly areattached to a uniweld frame and faceplate creating apenetration resistant neck with a standard throat of 3-1/4”.Coupling nuts are attached to the back of the face flange foruse with threaded rods. A mating duct collar with nutsreceive the threaded rod and are tightened accordingly.
INSTALLATIONSV49 is installed into the wall (or ceiling) with the threadedrods attached. A mating duct collar with nuts receives the rodand is then tightened to insure a secure fit on both sides ofthe wall. Optional attachment mechanisms are available forboth new and retrofit applications. Optional sleeve, lockingangle and rear operated opposed blade dampers may besupplied, if required. See pages A-14 and A-15 for InstallationOverview.
