High-Precision Shale Shaker Screen Replacement for NOV BRANDT & Axiom Process P/N AX120TF-120 (API 120)
100% Interchangeable with NOV BRANDT AX-1 and Axiom Process AX-1 Shale Shakers | 683 x 600 mm Dual-Standard Dimensions
Disclaimer: All original equipment manufacturer names, trademarks, equipment models, and part numbers (including NOV Brandt, Axiom Process, Axiom AX-1, and P/N AX120TF-120) are referenced solely for technical identification, dimensional cross-reference, and equipment compatibility. Our replacement shaker screens are independently manufactured, certified to API RP 13C standards, and are neither manufactured nor endorsed by the OEM.
Engineering Deconstruction & Fluid Optimization
As drilling reaches deeper intervals, abrasive silt and micro-cuttings degrade rheological properties, increasing mud weight and chemical dilution costs. Operating an NOV BRANDT AX-1 or Axiom Process AX-1 shale shaker with API 120 screens (OEM Part Number: AX120TF-120 / P/N AX120TF-120) delivers optimal separation performance, trapping drill solids down to 120 μm.
However, fine mesh screens are susceptible to premature fatigue failure if screen tensioning is inconsistent or if the supporting frame flexes under high G-forces.
Our Engineered Composite Replacement Screen (Cross-Reference Part Number: AX120TF-120) features high-tensile SS316L wire cloth tensioned over an ultra-rigid thermoplastic frame, delivering long screen life, zero mud bypass, and a 35–45% cost advantage over OEM pricing.

Engineering Advantages & Quality Control
- Three-Layer Diffusion Bonding: Combines a fine screening surface cloth with an intermediate flow-control layer and a heavy-gauge backing mesh. This triple-layer construction prevents wire fluttering, extending screen life under abrasive slurry flows.
- Rigid Composite Grid Support: The underlying structural grid maintains uniform screen tension across the deck, ensuring consistent 120 μm cut point accuracy.
- Thermal and Chemical Resistance: Formulated to withstand mud temperatures up to 110°C and synthetic drilling fluid additives without degradation.
Maintenance, Fleet Configuration & Deck Installation Guidelines
- Triple-Deck Fleet Configuration Guide: For fine-section drilling on NOV Brandt & Axiom AX-1 shakers, deploy a 24-screen tiered setup: Top Scalping Deck: 8 pcs AX100TF-143; Middle Buffer Deck: 8 pcs AX120TF-120 (fine silt separation); Bottom Fine Deck: 8 pcs AX170TF-94. Total compliment is 24 panels, yielding a total screening area of 64.92 sq ft (6.03 m²).
- Rapid Changeout & Labor Ergonomics: Weighing only 4.5 kg (9.9 lbs), our composite screens allow a single operator to complete a full 24-screen deck changeout in under 15 minutes, ensuring minimal NPT during critical drilling intervals.
- Debris Clearance & Clamping: Thoroughly scrape and clean the basket guide rails. Sand deposits beneath the frame can cause point loading. Drive locking wedges uniformly to maintain even clamping force.
Frequently Asked Questions
Q: What are the exact dimensions and weight of this AX-1 replacement screen?
A: The standardized dimensions are 683 mm × 600 mm (approx. 27" × 24"), with a net weight of 4.5 kg (9.9 lbs) and an effective non-blanked area of 2.84 sq ft (0.264 m²). It is 100% direct drop-in compatible with both NOV Brandt AX-1 and Axiom Process AX-1 triple-deck shale shakers.
Q: Does P/N AX120TF-120 maintain its API 120 rating across the entire operational life of the screen?
A: Yes. The rigid grid bonding isolates each individual cell. If an isolated section is damaged, surrounding cells maintain mesh integrity and the calibrated 120 μm cut point.
Q: Can this screen replace steel-frame panels on NOV Brandt & Axiom AX-1 shakers?
A: Yes. This composite frame panel is a direct drop-in replacement for original steel-frame units, offering lighter handling weight and immunity to frame corrosion.
