Robust Woven and Felt Media for Mechanical Shaker Baghouse Systems

Skytech Ultrafab Shaker Filter Bags are engineered for mechanical shaker dust collection systems where bags are cleaned by oscillating the bag top header, causing the filter cake to break loose and fall into the hopper. Available in woven polyester, nylon, and cotton sateen, as well as needle-punched felt constructions, shaker bags are manufactured with precise dimensions and correct tensioning to ensure effective cake dislodgement in each cleaning cycle.

What Are Shaker Filter Bags?

Shaker baghouses are one of the oldest and most reliable dust collection technologies. A motor-driven mechanism oscillates the top header plate of the baghouse, shaking the filter bags and flexing the media to dislodge the accumulated dust cake. Because the cleaning relies on mechanical flexing rather than compressed air or flow reversal, shaker bags must be constructed from media that can withstand repeated flexing without fatigue cracking — woven fabrics and lighter needle-felts are generally preferred over heavy pulse-jet felt grades.

Features and Benefits

• Flex-Fatigue Resistant Woven Construction: Woven polyester, nylon, and cotton sateen construction resists mechanical fatigue from repeated flexing during shaker cleaning cycles — outlasting needle-felt in flex-intensive shaker systems
• Correct Bag Tension: Bags manufactured with the correct diameter and length to achieve proper tensioning on the shaker frame — critical for effective cake dislodgement during each cleaning oscillation
• Multiple Weave Options: Plain, twill, and sateen weave fabrics balanced for the right combination of particle retention, flow rate, and flex durability for each shaker dust type
• Felted Options Available: Lightweight needle-punched polyester and acrylic felt grades for shaker systems handling very fine dusts where a woven surface filter is insufficient
• Chemical and Temperature Resistance: Polyester covers up to 135°C; nylon to 120°C; cotton for ambient-temperature grain and woodworking applications where natural fibre is preferred
• Custom Length and Diameter: Bags manufactured to any length from 1.5 m to 5 m and diameter from 100 mm to 250 mm to fit all OEM and custom shaker baghouse designs

Technical Specifications

Applications

• Woodworking and Furniture: Shaker baghouses on woodworking machinery and spray booth exhaust systems — cotton and polyester bags handle fine wood dust and lacquer overspray
• Grain and Agricultural: Grain elevator, feed mill, and agricultural product handling shaker dust collectors — cotton and polyester shaker bags for food-contact-compatible dust collection
• Plastics Processing: Injection moulding, grinding, and recycling dust collection in shaker systems — polyester bags for ambient temperature fine plastic dust
• General Manufacturing: Light-duty industrial dust collection in metalworking, assembly, and light manufacturing facilities where compressed-air pulse-jet systems are unavailable
• Chemical and Pharmaceutical: Small-scale shaker dust collectors in chemical pilot plants and pharmaceutical R&D facilities handling moderate volumes of process dust

Why Choose Skytech Ultrafab for Shaker Filter Bags?

• Woven and Felt Both Available: Both woven fabric and needle-felt shaker bag constructions available from a single supplier — the right media type matched to the dust and cleaning system
• Precise Tension Sizing: Bags manufactured to the exact diameter and length required for correct shaker frame tensioning — preventing under-tensioned bags that clean poorly or over-tensioned bags that fatigue quickly
• Natural Fibre Expertise: Cotton sateen shaker bags available for grain, food, and woodworking applications where natural fibre is preferred or required for application compliance
• Custom Weave Specification: Weave density and yarn count specified to match the particle size, dust load, and cleaning frequency of each shaker baghouse application
• Fast Replacement Supply: Standard shaker bag sizes and materials held in stock for rapid dispatch — important for the smaller industrial facilities that typically use shaker systems
