A mid-size single-shoe air and screen seed cleaner with 54-inch wide screens, a 6,400 CFM reverse-incline fan, and two configurable flow patterns. Built for commercial seed producers who need more capacity than a compact cleaner can deliver. Supplied and supported across Western Canada by Vistasort.
The Clipper Prelude 526 is AT Ferrell's mid-size single-shoe air and screen cleaner — designed for seed producers and grain processors who need more screen area and air volume than a compact cleaner can provide, without stepping up to a dual-shoe machine.
All screens are 54 inches wide. The top scalping deck is 34 inches long; the two lower decks extend to 60 inches for thorough sifting. The machine runs a reverse-incline back fan generating up to 6,400 CFM, with two independent air gate controls for precise aspiration tuning. A 3-inch square, 1/4-inch thick tubular steel frame handles sustained commercial operation, and replaceable metal screenways and rubber seals extend long-term machine life.
The Prelude 526 supports two distinct screen flow configurations. Select the pattern that matches your crop and separation targets — both use all three screen decks followed by air aspiration.
Both the top and middle screen decks scalp oversized material from the product stream, while the bottom deck sifts out fine material, weed seeds, and trash. Best for crops with a wide range of oversized contaminants that benefit from two scalping passes.
The top deck scalps. The middle deck splits the product stream — scalping on one side and sifting on the other simultaneously. The bottom deck sifts. This configuration produces four distinct fractions from a single cleaning pass, maximizing grade separation.
The Prelude 526's single-shoe assembly processes grain through an infeed, three screen decks, and a dual-gate air aspiration column — removing both mechanical and aerodynamic contaminants in one pass.
The vibratory inlet feed hopper with adjustable internal gate delivers a uniform product stream through the air column and onto the screen decks. Electronic variable speed option provides precise feed rate control.
The top 54" × 34" scalping deck removes oversized material from the product stream. Oversized material exits the machine front while good product falls through to the lower decks below.
Depending on the chosen flow configuration (Scalp-Scalp-Sift or Scalp-Split-Sift), the lower two 54" × 60" decks perform additional scalping, sifting, or split-sifting to separate the product into its final fractions.
Throughout operation, Clipper's new-style ball trays continuously prevent screen blinding — maintaining consistent throughput on all three decks without operator intervention or production stoppages.
Two independent calibrated air gate controls provide precision pre-suction and after-suction aspiration. The reverse-incline fan generates up to 6,400 CFM — removing dust, chaff, and lightweight material before clean product is discharged.
Built for continuous commercial operation with full operator control over separation accuracy — from feed rate to airflow to screen selection.
3-inch square, 1/4-inch wall tubular steel frame provides the structural rigidity required for sustained high-volume commercial operation — resisting flex and fatigue through years of continuous use.
The reverse-incline back fan generates up to 6,400 CFM with a drive setup that can be easily reconfigured on-site to match local electrical supply and air volume requirements.
Two calibrated air gate controls independently adjust pre-suction and after-suction aspiration — allowing fine-tuned removal of lightweight material tuned to your specific crop's aerodynamic profile.
Fixed-speed vibratory inlet with adjustable internal gate as standard. Electronic variable speed option available — controllable from a side-mounted panel for single-operator feed rate management.
Rubber balls prevent screen blinding continuously during operation. New-style trays allow screens to be changed without removing the ball trays — a significant time-saving advantage during crop changeovers.
The air lock discharge trash spout maintains consistent air pressure inside the separation column during continuous operation — preventing backpressure fluctuations that could affect separation quality.
Metal screenways and rubber screen seals are fully replaceable — extending machine service life and simplifying long-term maintenance. New-style shoe hangers and drive connectors ensure smooth, counterbalanced operation.
All screens use the standard 54" × 26" section format, with over 150 perforated metal and wire mesh sizes available — covering every major grain and seed crop grown in Western Canada.
Motor packages available in 50 or 60 Hz, single or three phase, TEFC or explosion-proof configurations — matching the Prelude 526 to the electrical infrastructure of any Canadian processing facility.
Configure the Prelude 526 to match your operation's specific needs — all orderable through Vistasort.

The Prelude 526's 54-inch screens and 6,400 CFM fan handle a wide range of Western Canadian crops at mid-to-high commercial throughput rates.
The 54-inch wide screen decks process cereal crops efficiently in both scalp-scalp-sift and scalp-split-sift configurations — removing oversized material, fines, and weed seeds to meet export grade requirements for wheat, barley, oats, rye, and durum.
The split-sift flow configuration is particularly effective for pulse crops — separating whole peas, lentils, and chickpeas from splits and undersized seed in a single pass. The dual air gates provide precise removal of lightweight broken seed and debris.
Fine-screen options for canola and other small oilseeds take full advantage of the 6,400 CFM fan and dual independent air gates — delivering precise aerodynamic separation without over-aspirating small, healthy seed.
The Prelude 526 is sized for commercial seed plant use — providing the screen area and airflow volume required for sustained multi-shift operation. Pairs effectively with a Conquest 286 pre-cleaner upstream for maximum line efficiency.
For certified seed producers, the new-style ball trays and replaceable screen seals enable fast, thorough cleanout between varieties — critical for maintaining certified seed purity standards and preventing contamination between lots.
High-value specialty crops with strict purity tolerances benefit from the configurable flow patterns and dual-gate aspiration. The machine can be tuned for each crop's specific separation requirements without major mechanical changes.
