Ruskin: Single-bladed bubble tight isolation damper

Ruskin just lately introduced the BTD830 bubble tight isolation damper, the corporate’s latest addition to its bubble tight product sequence. The BTD830 is an oblong bubble tight damper ultimate for purposes the place extraordinarily low leakage is required. The oblong design provides extra free space, decrease strain drops, higher airflow in comparison with spherical or oval dampers, and is a lower-cost different to different bubble tight dampers.
 
Typical purposes embrace biotech labs, meals processing operations, industrial course of programs, laboratories and nuclear energy vegetation, together with medical, navy and pharmaceutical services.
 
 The BTD830 is bubble tight in response to the AMCA 500-D customary with a most velocity of 4,000 FPM, a static strain of 10.0” w.g. (2.5 kPa) and a temperature vary of -40°F to 250°F (-40°C to 121°C).
 
Damper sizes vary from 6” x 6” (15.2cm x 15.2cm) to 36” x 16” (91.4cm x 40.6cm). The flanged dampers may be mounted for horizontal or vertical airflow, and customary or customized mounting gap configurations can be found.
 
Commonplace options embrace: 

• Rectangular flanges
• Painted metal channel body and blade
• Middle-pivoted, double-skin blade with 12ga minimal thickness welded to a full-length axle
• Stainless-steel sleeve bearings bolted to the damper body
• Axle seal built-in with the bearing meeting
• Discipline replaceable stable silicone blade seal that’s mechanically mounted to the blade
• Polyamide epoxy end

Optionally available options embrace sq. flanges, a mil-spec body or blade (304SS, 304LSS, 316SS, 316LSS) and mil-spec axle (316 SS, 316L SS) or end (304SS, 304L SS, 316SS, 316L SS). Ruskin can provide and mount actuators and restrict switches as wanted, together with:

• Guide worm gear with handwheel
• Direct-mount, business grade
• Electrical, quarter-turn rotary (fail in place, battery backup, spring return – 24V, 120V, 230V)
• Pneumatic, quarter-turn rotary (double performing or spring return)

Every BTD830 damper is totally cycled and examined on the manufacturing unit previous to cargo in accordance with AMCA Commonplace 500-D. Ruskin performs bubble leak testing to 10.0” w.g. (2.5 kPa) earlier than cargo to make sure leakage efficiency. See the product knowledge spec sheet for strain drop data, per the AMCA 500-D-18 check customary.
 
The BTD830 is manufactured in an ISO9001 licensed manufacturing unit and comes with a 5-year restricted guarantee.
