Fan deltas are like alluvial fans except they dip their toes in lakes and shallow seas. So, in addition to the alluvial component, there is subaqueous deposition down a relatively steep, angle-of-repose slope. Delta Electronics is committed to developing innovative technologies and solutions for a better tomorrow. Delta Breez is the one-and-only brand of residential bathroom exhaust fans that can deliver a powerful combination of high-performance, quietness, state-of-the-art brushless DC motor technology, and affordability in every fan. Delta Breez ventilation fans are ENERGY STAR ® qualified and some have been designated ENERGY STAR Most Efficient 2021, except for BreezRadiance series with Heater, which have a powerful 1300W/1600W heating element for warmth and comfort. Superflo fans can be used in many of the Delta fan series. The Superflo bearing system: Prevents oil leakage; Greatly prolongs the life of any fan; Runs longer than standard fans.In the Delta fan naming system, the second digit “U” signifies a Superflo fan. The Superflo AUB Series fan L10 life is guaranteed for 50,000 hrs @ 40. The Delta Fan and Thermal product line offers a full range of axial fans, blowers, and thermal management products. The unique patented blade design and innovative structure greatly increases cooling performance and reduces system noise. Delta fans and thermal products can be found worldwide, serving a wide range of industries and organizations.

Two types of coarse-grained deltas are recognized: fan-deltas and braid deltas. Fan-deltas are gravel-rich deltas formed where an alluvial fan is deposited directly into a standing body of water from an adjacent highland. They occupy a space between the highland (usually a fault-bounded margin) and the standing body of water. In contrast, braid deltas (here introduced) are gravel-rich deltas that form where a braided fluvial system progrades into a standing body of water. Braid deltas have no necessary relationship with alluvial fans, as exemplified by fluvioglacial braid deltas. Braid deltas have previously been classified as fan-deltas even though the geomorphic and sedimentologic settings of the two systems can be vastly different. Braid deltas are a common present-day geomorphic feature and are abundant in the geological record.
Delta Pc Fans
Fan-deltas and braid deltas can be distinguished in the rock record by distinctive subaerial components of these depositional systems; the shoreline and subaqueous components of both are similar. Fan-delta sequences have a subaerial component that is an alluvial-fan facies comprising interbedded sheetflood, debris-flow, and braided-channel deposits. Fan-deltas produce small (a few tens of square kilometres), wedge-shaped bodies of sediment, commonly displaying high variability in paleocurrent patterns and abrupt changes in facies. The deposits are generally very coarse grained (with large out-sized clasts), very poorly sorted, matrix-rich, polymictic, heterolithic, partially cemented by penecontemporaneous carbonate, and have low porosity and permeability. Braid-deltas, in contrast, have a subaerial component consisting entirely of braided-river or braidplain facies. Their deposits display better sorting, roundness, and clast orientation than do fan-delta sediments; they lack a muddy matrix; they display size grading and bar migration; they commonly have a sheet geometry with high lateral continuity (tens to hundreds of square kilometres); and they exhibit moderate to high porosity and permeability. Valuable paleogeographic and tectonic information concerning the proximity of highlands and major fault zones may be misinterpreted or lost if these two coarse-grained deltaic systems are not differentiated.
