SHAKER FILTER BAGS

Purpose-built for the gentle, continuous cleaning cycles of reverse-air baghouses, Masturlal RABH bags are offered in the two fibres that have proven most reliable in this duty—fibreglass and polyester—each engineered to deliver sub-5 mg/Nm³ stack emissions and long service life.

Media Options & Performance Window

Fibre Continuous Temp (°C) Distinctive Properties Typical Duty

Polyester. 150 Excellent flex life, cost-efficient Grain, woodworking, general dust

Antistatic Polyester 150 Surface resistivity < 10⁸ Ω Flour mills, sugar, plastics

Acrylic 120 Moisture-tolerant, acid-stable Fertiliser, dryers, tobacco

Para-aramid Blend. 190 High-temperature endurance Asphalt, foundry shakeouts

Selection Workflow

  1. Process Audit – gas temperature, humidity, dust load, shake frequency.

  2. Media Selection & Sample Bag – lab data, 90-day pilot trial.

  3. Production & Delivery – guaranteed lead time from our 30 000 sq ft plant.

  4. Commissioning Support – on-site leak test, ΔP optimisation, operator training.

    • Emission level: ≤ 5 mg/Nm³ (field-validated)

    • Fibre options: lofted polyester, acrylic, antistatic polyester, para-aramid blends for elevated temperatures

    • Operating window: –20 °C to 190 °C, dependent on fibre selection

    • Dimensions: diameters 125 – 300 mm, lengths to 10 m (custom sizes on request)

    • Cleaning method: mechanical shake or vibratory frame, ≤ 300 cycles / h

    • Quality assurance: ISO 9001 & 14001 facility, 100 % seam-strength and air-permeability testing

    • Single-Seam Tube Precision-needle-felt tube with integral seam tape to prevent bypass.

    • Loft-Retention Finish Controlled fibre crimp and calendaring allow rapid dust release at low shake amplitudes.

    • Toe Guard / Wear Cuff Abrasion-resistant layer protects against inlet scuffing, extending service life.

    • Surface Treatments Singeing, glazing, PTFE dip, oleophobic, antistatic or flame-retardant—all applied in-house for perfect process fit.

    • Custom Top & Bottom Ends Loop, strap, clamp or corded cuff tops; sewn or reinforced discs, cones or spouts at the bottom—matched exactly to your shaker frame.

    • Milling & grain handling facilities

    • Sawmills and MDF plants

    • Fertiliser & tobacco dryers

    • Foundry shakeout lines

    • Asphalt batch plants

    • Stable ΔP High-loft batt ensures fast re-aeration after each shake cycle, keeping fan energy low.

    • Extended Flex Life Optimised scrim and seam geometry withstand > 1 million shake cycles without cracks or pinholes.

    • Proven Cleanliness Consistently holds stack dust below 5 mg/Nm³—even on fine, clingy dusts such as flour or carbon black.
